Only props from Xoar I have tried are 18 x 10 and they are superb. Probably will replace my ProZingers through attrition with all Xoar. The finish is nicer and, so far, they are balanced right out of the wrapper.

I like APC for my 2-cycle glow engines. I've been runing Zingers in my .70 4-stroke and may try the Xoars in that as well.
