This thread has me quite interested. I play with an Elk Master, and have been for about 15 years or so (I come from a snooker background and that's all I knew, and what I got used to). I play at a 736 speed, so take my opinion with a grain of salt, the top players are probably where they are because they've been able to harness the power that a layered tip has to offer, but here are my thoughts all the same.
Early on in my pool playing life, I switched to a Moori Medium and really noticed a difference in how much more "action" I got with it. I was able to draw the ball much more effortlessly, which I believed to be a great thing, because I could hit the ball with more control and not have to pound it, and still get a the cueball to do what I want. You would instantly think that this is a huge advantage over the cheaper tip and to a lot of degrees it is. However, something I haven't seen a lot of people talk about is the reduced accuracy that comes with a tip that gives you a ton of action. If I'm getting all that extra action "for free", it also means If I hit a ball "bad" with spin, I could throw it off line.
What I'm saying is, with the Elk master (or Le Pro, Triangle, other non "juicy" tips), I have more margin for error when pocketing balls. My style of game is based on throwing balls in, I believe it gives me a MUCH higher margin for error than simply hitting a ball with no spin. The fact that I get less "action" with my Elk Master means if I catch a ball thicker than I intended, the spin does a "little" correction and throws the ball in. With a layered tip, I find when I hit it bad like this, it gets thrown too much.
The long and the short of what i'm getting at, that I feel isn't addressed too much is, the more action you can get with a tip the more accurate you have to be when pocketing balls. Example, If you have an almost straight in shot and under pressure you put a hair of unwanted english on the cueball, guess what, the object ball can be thrown off line very easily. Tips like the Elk Master are far more forgiving. If I hit that straight in shot "bad" by putting a hair of unwanted english on the ball, luckily for me, not much spin has been imparted on the object ball and it still travels along the path I intended.
Don't get me wrong, every year or two, I get the itch to try out a "juicy" tip, and I do really fall in love with how easy some shots are to execute with all that tip power, however, the "forgivingness" I get from having "dull" tip really swings it for me and I usually end up cutting that $50 tip off after a few days. Sure, having easy access to the big draw shot and super spin are nice to have, but I believe it comes with trade-offs that aren't worth it. I can still come with the big draw shot (just takes more muscle), but if I'm in line the way I should be, I don't need to call on it too often.
Thanks for reading, I would be interested to hear opinions to my thoughts on the this topic
