yup the coke bottle glasses and shaky hands are no good. Grab a 17-20 year old kid that can play, i mean a real player who knows what to do and let him rack, he would have perfect racks fast. The old guys dont see the balls come apart when they lift the rack off-thats what I noticed is the biggest issue. its just a better solution to the problem, not a knock on them, hell i'm 43 and Its harder for me to rack than it used to be. gotta keep it real, best eric
