Ive been playing for 25 years and always aimed by feel until yesterday. I decided to look into this. I watched this video for free on YouTube.

Turns out this is a friend of mine. I had no idea he did this but I do know he is a hell of a player and has spent a lot on lessons.
With in an hour using this method became 2nd nature and I almost felt like it was cheating. I don't have the best eyes any more but you barely need to aim. At the end of the day I was aiming c to e then after pivoting back to center....closing my eyes and firing and the ball was hitting the back of the pocket every time. It works...period. I don't know why and frankly don't care.
Heres the thing... If you don't have solid fundamentals this nor will anything like this work. You also of course have to make adjustments when you apply English. I remember last year watching the gentlemen who teaches for predator talking about how systems help you play under pressure. That the average guy who plays by feel Will be in trouble when the cheese is on the line. When that adrenaline gets flowing and the preasue is on it's tough to clear your head and still let nature take it's course. Systems allow the average guy to push through the haze and still succeed.
Spidey is a friend and your just finding out about this, lol.
