As of now im throwing a cell at 500 grit with polish , a gamebreaker at 2000 grit , a gamebreaker at 4000 grit with polish , and a clash at 4000 grit with polish. Also have an Ebonite maxim spare ball. So, I wanna tap into the intelligent minds on these boards and ask if there are any holes in my arsenal. I'm bowling two summer leagues right now. One league hosts a broken down ths, while the other league provides challenging sport shots. I'm a lefty with medium revs and 15 mph ball speed.
