Okay, so 2 things i noticed yesterday. I have always known i muscled the ball forward, not waiting for the ball motion to change direction in the (short) backswing. Yesterday during warm up i tried waiting for the ball to start swinging foward itself instead of muscling it back forward and immediately noticed a huge increase in revs. It was still not hooking much but my revs doubled or even tripled (still not much though :p). I tried to change back to my normal approach because i was not hitting my mark but this screwed up my game completely and i did not score very well. but oh well
. At least I know this is definitely one of the limiting factors to my current throw.
Second thing i noticed is when i try to do this Joe Slowinski release drill, with my 0 thumbpitch i cannot seem to get out of the ball cleanly. Because of the short backswing i know I am not squeezing the ball, but it hangs a tiny bit before it comes off. I have always felt better throwing my spare ball (which is like very old). I tried the release drill with this ball and i can get my thumbhole much looser, still feel comfortable letting the ball hang and it will not fall off. AND it will come of my hand cleaner during that drill.
Because it is so old i think i still have reverse pitch in it, since i started bowling with reverse pitch.
I will probably ask my new driller (the old one retired) to have a look at the pitch in the ball, and drill my new ones like this.
