I'm totally befuddled. You're a fine poster. So is BBB. I simply don't believe you when you say straight in shots are the easiest of all shots. Please don't feel slighted. These forums are filled with fine posters who believe as you do. I rarely tell posters such as you I don't believe something they state. It's just that there is something very odd that goes on around here when the subject of straight - in shots comes up.
I have zero problems recognizing shot lines. I don't think about my dominant eye or non - dominant eye or any of that stuff. A while back C J Wiley recommended to me an exercise where I only look at the OB while shooting. When I do that, the CB is basically invisible to me. I only know where it is and hit it by feel.
Not only do I hit it by feel, but I use T.O.I while only hitting it only by feel. I'll say I make 75 to 80% of the shots I would make if I was looking at the CB.
When I shoot straight in shots, I know if I made them the instant the ball leaves the tip. I can tell if I came back perfectly straight with the cue and came forward perfectly straight also. If I come back straight and come forward straight I make the shot EVERY TIME! If there's the slightest "swoop" in my stroke I miss the shot EVERY TIME!
So after you guys have figured out your issues with dominant eye and shot lines, etc., which is something that I very fortunately don't have to deal with, you're still in the same boat I am. You still have to come back perfectly straight with the cue and come forward perfectly straight with the cue.
You say this shot is easy for you. I say anyone who finds this shot easy must shoot at a pro level; for the simple reason that I find it to be the ULTIMATE TESTER. If you don't shoot a the pro level, I don't believe you. Once again, please don't feel slighted. There are many other fine posters who claim they find this shot easy and I don't believe them either. I hope I'm not offending you or them; rather, I think there's just something funny going on with the straight - in shot and all discussions of it around here. Maybe we'll discover where that "Funniness lies."
.......And hey.....I've been wrong before!
