I always had great luck with MSC 26X10's. You can get about all the props mentioned above from Desert Aircraft.

Finally I run into someone else running a 26X10 on a da100 - I am not crazy or stupid after all. I had to lie to dave at da - told him it was for zdz80 or he would not have sold me one. I flew it last summer in sacramento 300' elevation it chopped up that wet heavy air like it owned the place no loss in verticles, tail touches were easy like it was hanging from a string.
