Hi Snakster - You have a pretty complete arsenal. If you can provide the Dual Angle layout for each ball I will evaluate. If not just the pin location, Up and how far, Out and how far, down and how far. I have reviewed the engineering for each of your balls. A 170 average athlete throws several strikes per game and makes a few spares. I would believe that your main issue is spare shooting. You need a plastic spare ball. Use for as many spare opportunities as possible. Remember that wood lanes are hooking lanes. Reactive Resin balls are Hooking balls. As you stated you kill the release to flatten the shot out. The resin ball with RG's that you have will want to hook! Respect the engineering of each ball. Happy Memorial Day Holiday! Gold Coach Denny
