thats what i'm having trouble a month ago. for some reason i can't roll the ball correctly i'm turning the ball rather than rolling it. started the pba shot a month ago. never bowled anything but house shot but its reall different. now that i've been practicing getting my release down and making the ball to roll. i'll do that this monday nite for my pba shot. also try to use my cell and rogue and play the outside shot and create that dry shot for me. That's also my problem have the equipment but afraid to use them cause too conscious about people talking why using that ball vs that ball. so my friend who gives a f### use it if you need to. its also confidence issue too. Don't now if all of you disagree with me or not. with so much practice been averaging over 200 this past month with one bad week didn't shoot 500 with high of 755 and just shot 697 subbing last friday. using cell pearl. by the way my equipments are all rotogrips
