Sounds good! are you just going to swap all the internals over?
I know a few with the G2 D60s and they love them, very solid and are a direct bolt on replacement. I havent seen anyone with a Prorock though so I donno if they are that easy. I would maybe call them to see what else is needed. Polyperformance has them and can prolly answer all the questions as well.
