Honestly, only lots of work will let you play ANY line. You have to be willing to leave behind what you are doing for something you may not have even tried to do before. You can really play inside with any ball, just a matter of hitting the same mark everytime. Yes, you need the right ball in your hand to be successful from any line, especially inside, but at the start, I would practice moving inside a picking something to hit. The more comfortable you get playing inside, the easier it will be when you pick up the right ball for you to tht with. However, even with that said, don't try to force a ball when the shot isn't there. I still can play down and in with a GP2 I have, in fact, it is the 2nd one I drilled and shot 813 the first night in league with. Just because you are getting a hook in the box doesn't mean you move inside. Find a line with your Sling, then, after hitting the pocket consistantly, pick up the GP2. Adjust from there, it may be 5 boards, it may be 7, and so on. Keep moving until you hit the pocket consistantly. REMEMBER: The GP2, like any hook monster, needs oil to work. A broken down shot with little head oil will make the ball burn and lose its energy very early, making it look like it doesn't move much on the backend and will hit like a pumpkin.
