Larry,
The reason I don't respond much to those kinds of queries, is I fall into the group Doc is describing. I can honestly say, I have never used any type of syatem, for any phase of my pool game.
The shot you are describing (2 rails at the 14 ball) is made tougher by being over a ball. Were it not for that, in my day...I would bet even money, I would hit the 14 fairly solid, and drive it uptable, or towards the stack.
Not saying for some people, a "system" might make them more comfortable while over the shot...but I have always felt more comfortable by just "feel"
This goes for all types of shots. When I was turning out, there was no such thing as CTE, CID, BHE, "pivoting" or all the other alphabet soup you hear these days...Thats my story, and I'm stickin' to it.
PS..I would be very surprised if most players, anywhere near my age, or even quite a bit younger, do not "feel" the same way...
