I haven't thrown a NanoP but from what I have saw it looks like the Nut's and Nut's Pearl gear up sooner than a NanoP. I think its safe to say the 900 Global balls just start up soon than many Storm pieces.

My Nano Pearl goes fairly straight also. I tried it at 2000 and liked it even less. It rolled earlier and I think cerry was a little worse for me. I am bowling on a heavy condition though. I ordered some neat pads and some magic shine so I can try tweaking the cover some more. I just think I need more of a medium condition with some clean backends to get the ball to work.
