I've been reading this extremely useful and practical discussion. I share similar problems as the gentleman who started the thread and I've been working with my stroke and rest of the fundamentals since a long time (took 3-4 years off from pool though)
i have mixed issues in grip/alignment/stroke, experimenting on many things - finally I tried a number of advice written here and from what I've learned, mainly:
1) to follow through all the way and looking at the fellow's most recent video and remembering the sweet follow-through stroke of pros, a few of those shots and suddenly I feel in dead stroke and finally get that "feeling" of playing the proper way.
note: But this happens mainly when I do a bit more "energetic" strokes, it's as if I'm making sure that the ball will go in and prepare my "sweet" follow-through while doing so, but it seems to only work on the "more energetic" strokes. Then afterwards when I started practicing the 14.1 game, a game where you need to slow down - I "slowed" down the energetic strokes and almost instantly the "sweet" in-the-money shooting slipped away, and I was left with a mix of the old habits of stroking slower , while trying to be as fluid as possible, but didn't feel "on-the-money" anymore.
2) adjusting body position to put the back foot on the line or slightly inside the line, as FranCrimi mentioned to me in another thread - this mainly helps the swing to be completely free and away from any chest area.... still working on it though it's really not as easy as it sounds.
3) while focusing on the follow through I also discovered that I needed to ABSOLUTELY make sure that the grip was loose during follow through. I seem to be quite loose in 95% of my stroking but it seems there is some slight minimal tension during the hit of the Q-ball and afterwards. It is more subtle though than the gentleman who started this thread. It is rather very very subtle - meaning it's a "grip" thing, meaning the grip during impact is probably not as loose as it should be, but working on loosening the grip and by shaking the forearm-wrist a little bit before coming into the shot (just as Archer does), combined with remembering that follow through - I picture myself that the cue stick is moving like a train through the q-ball and it works, don't know why I have a train in mind but it helps to focus on getting the cue thrown smoothly throught he q-ball... etc.
4) even after mastering all these, even when I feel "in-the-money" , it seems long straight shots or near straight in long shots which are at a distance of at least 4 diamonds , the object ball misses the pocket so it seems - this though I'm almost sure has somehting to do with my eyes, well you mentioned in the thread about the 3rd eye trainer and so I went ahead and watched a few videos from joe tucker. then while practicing today and missing some long shots which were almost straight-in or with a small angle, I had a feeling it's something with the eyes.. because at that point i was pretty much in a sweet stroke making all sorts of balls. I would also make the longer shots even the straight-in shots, but it seems when the object ball was near the rail i would miss it about 50-60% of the time etc. this subject is a bit complicated but i'm sure you guys know what i'm talking about..
about the eyes "misleading" our aim, the gent in this thread mentioned something about getting the 3rd eye trainer from joe tucker, then by curiosity i saw a few videos about the 3rd eye trainer where joe explained the problem of aim and eyes that most players seem to be having.. but i don't think that practicing your eyes 10 minutes a day will solve the problem, it seems to me you're forcing your eyes to be used both 50-50, what's wrong with playing using the dominant eye?
I found this video from Dr Dave's about the vision center to be helpful:
http://youtu.be/680o8EChP_o
i'll use that drill and check if the aim is due to vision not being aligned with the shot properly, which causes my frequent misses in longer near straight-in shots..
but really I find... enough practice should make our "aim" adjust automatically... but maybe not! . so it's tricky. perhaps practicing lots of straight long shots with low center and high spin, should be a good practice for adjusting all the fundamentals in one piece. you see joe tucker himself doing those kinds of drills.
the same ideoogy on stroke practice is proposed by bert kinister who's instructions I happened to watch a few years back when working on my stroke. he gives a few drills on long straight in shots, first one handed , then two-handed then two-handed backspin all the way back.
I remember I used to practice all day in that one-handed drill and finally got to make the ball almost 10 times in a row one handed, 4 diamonds apart. Bert emphasized that when you do that, then your body and eyes are positioned exactly how they should be for your aim to be perfect on that object ball.
on a side note.... I wouldn't be so sure that the one-handed exercise really improves your fundamentals. that's because when you go back to a two-handed position, your body's balance is different from the one-handed shooting. ..
--------------------------------
anyhow, going back to my practice, after getting that sweet-stroke flowing through, feeling like i'm cutting butter through those balls, following through, feeling like a champ, then I decide to put that in a game of straight pool... what happens is a slight dissapointment.
so after 1-2 hrs of practicing my stroke etc.. , I start a 14.1 game, and I start struggling with shots, because i guess i'm focusing still on my fundamentals, and also trying to focus on the game... it's kinda hard to do now I realize.
then while playing I probably unconsciously adjust adjust adjust,to the missed positions and missed balls, and finally the sweet follow through stroke is partially gone, mainly because I've slowed down the whole stroking and aiming process while thinking about my game.
looking back at all this, I realize it's probably best to focus on fundamentals and that stroke to get it real solid, and then move on to the 14.1 game (and other games)... somoene here mentioned that behavioural scientists claim it takes about 3000 repetitions to get something into a habit. but what about if you've been playing for "x" amount of years" , in my case i'd say 5-6 years. the adjustment period could be even longer than 3000 repetitions of the "new stroke'. plus, even when practicing the new fundamentals, you have some residue from the old habits and I'm sure it can take way more than 3000 repetitions to really master the newly adjusted stroke (with all it's small details - grip-stance-the way you do your practice strokes, the speed of your practice strokes, approach to the table before the shot and alignment with the object ball...etc).
when I first started working on my fundamentals I thought I was on for a short ride but now i realize that ride could be way longer than expected. perhaps a really solid and frequent practice until you get it as second nature, is what should be done. what do you think FranCrimi?
