Ron,
Super Six, not a Rocket, but I just swapped from a Hartzell D-Twist Paddle to a Hartzell BA. Gained the hoped-for 4-5 knots, and went from the thump to butter smooth. Great prop. But that's the 2-blade world, and you opened with three blades...
Just for comparisons sake in your search, I chased Mark around with his MT last year and traded races with him. With his new Hartzell BA, I couldn't touch him at Reno, so his speed gains are real. Now of course, his spray bars and a few other Team Rocket Skunk Works mods may have helped too
, but as he said, the lion's share was the prop (MT to BA).
It'll be interesting to see what speed Greg Nelson gets if he ever switches his MT to a BA...though he has been heard to say "never", because the MT is so smooth. I think he was waivering after Mark's performance in Reno.
I too would love to see a side-by-side with the WW! I love the elliptical lines of that prop, and have always wondered if that shape adds speed, the way Paul Lipps' Elippse props did. Rick, that is one purty prop for that gorgeous machine, that's for sure. 3 blades are just dang sexy, for sure!
Good luck Ron...its a nice dilemma to contemplate!
Cheers,
Bob
