Don't let anybody fool you. Bolly props are good. There only problem is ripping at high RPM. This can be made better by reshapping the tips. For the 3.2 Brisson says 22 X 8 is the largest prop they recommend. A 23 X 8 or 22 X10 should drop the speed about 500 RPM's . 3W makes a prop that is almost identical to the Menz. Both would be a good choice. I have 3W and Mejhlik props and to be honest they are very close in performance.
I hope this helps.
