Futurase, I have about $200 worth of props (MSC, NX, Bambula, Menz, ProZinger, Zinger, Top Flight) I tried on my DA50 in sizes from 22x8 to 24x8 and everything in between from 8-12 pitch. And I have always gone back to the Menz 24x8. It is simply the best 3D prop out there, for me - AFTER you get the engine broken in. I read all the stuff about how this prop or that one was better than the Menz. Just save yourself a lot of grief and break it in on the Menz 22x8 then go to the 24. Now if money is no object then you can start to look at the CF stuff I guess, but thats another issue I haven't tried yet.
