Been bowling for about 18 years - carrying a 204 avg and currently using a 16lb Columbia Throttle.  My ideal shot is to be able to play middle out and come back into the pocket...but at the house i bowl at it always seems to be a different shot and since I am a big guy and like to throw the ball hard, I always have to change my shot and my ball speed constantly....Can anyone recommend a ball and a drilling style to help me out....I don't know anything about drilling and I take it to my local pro shop and explain how i play and they drilled the Throttle for me and it only seems to hook when its medium to light oil...I need a ball I can throw hard and it'll hook in heavy oil...I also need to know how to have it drilled...please respond either here or to slitz22@aol.com...Thanks
