We switched from a two blade to the three blade indigo prop a few years ago on our C&C35 MKII. I love the control in reverse and it operates at cruising speed at about 2000 rmp, which is about 80% of full throttle and gives me that reserve when conditions are bad. Also smoother than the 2 blade.
I have never been able to duplicate the 1 kt speed increase people claim with a feathering prop (by comparing speed between freewheeling prop and prop stopped in gear) so I am dubious that there is really such a benefit. In any event, we mainly cruise, so it doesn't make that much difference anyway.
