This is really weird but this is exactly what I am experiencing. I stroke best when my rear hand (I'm a leftie) is fully rotated clockwise like its bending over backwards, and the knuckles are facing straight up instead of straight down. The fact that it is firmly locked gives my stroking arm some much-needed support.
I also tend to hold the cue towards the butt where the weight is concentrated, so that when I pull the trigger, the full weight of the cue goes forward, much like a battering ram, and very little push is provided by my stroking arm.
yeah i hold closer to the butt too but only because i feel i dont have to hit as hard the further back i reach and can just stroke through. and yeah my knuckles face the ceiling. weird stuff. pinoy?
