Wanted to let everyone know the new prototype I happened to test outperformed my 2011 ProV1 on every shot. It went 10-15 yards further on all my clubs, having penetrating trajectory. I think there is a bit more spin than the 2011 model, which means you can land it a little closer to the flag stick and have it stop. I think this is a great prototype and I would do little to change it because it's already good!! Good job to Titleist R&D.
