I tried a 14X6MA today and I liked it a lot better. It still had tons of torque but would pull out of a torque roll a little faster.

Whats strange is that I was getting almost identical RPM's out of the 2 props. Both around 9500 on 10%. Its a new engine and is still being run rich so I think by the time it has a few gallons through it I hope to get a good 10000 (which is considerably higher than I thought I would get!!!).

I will try the 15X4 next.
