i would think that since you're just starting back, you might want to keep it simple . . . meaning using pretty much the same release for every shot. pick up a plastic ball so you don't have to worry about hooking it. there are alot of choices, from cheapo balls to clear covered plastics with great designs and logos. some people use a lighter spare ball, but i'd suggest sticking with the same weight.
i use my strike ball and flatten out my wrist when i throw at the 6 & 10 pin. i'm gradually transitioning into more straight shots for spares, unless there's a sleeper pin, but for now i'm hooking at most spares.
welcome back to bowling and enjoy!!! glad to have you here!!
