i've been using xoar and menz 18-6 on a 72"yak w/160 os, the menz spins up better on that set up. the xoar is very good but the menz is beter. on my DA 100 on a heavy (32lb) 35% yak the menz 27-10 was the best i had found untill i got my hands on a Vess 27a you wouldn't believe the differance, vert pull out from a houver is soooooooo much better.

differant engines, shape-size-weight of plane,and flying style will keep one size or brand of prop from working for everyone. Menz,Bolly, Xoar, Vess and others have great props we just have to try them on and see how they fit our needs.
