It's funny how a prop that works well for one boat doesn't for another. My TS2 runs well with a 215. Turning is predictable and it has yet to blow over. I'd like more speed, but it's pretty much even with the other TS2s and I'm in the middle of the club race series. I'm focusing on consistant driving and leaving the setup alone. I've got a "special" modded 1440 that I'm going to try the next time I take it to the pond. It's supposed to work very well.
