One motor will not work. Wtf

I've been looking for opinions here, but I can't seem to find what I'm looking for.
I'd like to know what props people are using. I have some gemfan poly fiber 2 blade that are decent, and some abs triblade that are much worse. Have not tried the spendy carbon props, but so far I like the 2 blade. It could be the material.
So, what is everyone using. Am I just not finding the topic on this forum???

DAL cyclone or Dal 5045x3 BN.
Racekraft 5051x3 & when my stash has ran out then I will try get some emax Avans. I don't race so I get longer out of them.
