Tyler and Dud,
Without over-anylizing the shot, it is not easy to execute IF you are trying to draw to the side rail, for shape on the 15. That shot requires a good solid stroke, but is doable..The shot I am proposing, is coming off the duece, and knocking the 15, up table. This looks to me, like a perfect angle to do this..IF (big if) you shoot the correct speed..I think you both know, the firmer you shoot, the more bounce and deflection you will create, as you come off the 2 ball..
Dud, I would venture to say, in your experiment, you did not shoot hard enough, thats why you only grazed the 15...The angle presented in RBL's layout, would make me concerned more with 'double-kissing the 15, rather than hitting it too thin..I, in no way, endorse drawing the cue ball to the side rail first. To me that increases the difficulty for a sucessful outcome, several fold..Its all about speed..And I (used to) have a good enough stroke to do whatever I wanted with the cue ball..
Super 'Ballsy' Duck <--Always shot at a white flag like THAT ONE !!..
Caution; for AB lover's..This may NOT be Artie's shot choice !
PS..Dr. Bill, either those type shots are starting to look real tough for you, (in your dodderage)..or you are trying to convince the Hacker, he'll be allright leaving them for you..(you can PM me, which it is
)..
..ROTF LMFAO
