What props should I order?

I have these in my cart....

437/3
X637
X438



Are these good choices? For the mini

Those look to be a good choice. Only thing people have said that you get a lot more lift with the 3 blade props and recommended me to stick with 2 blade props on Catamaran hulls. Maybe someone else could shed some light on that.

I run a X438s/b on my Fighter Cat Lynx which is the same hull as your mini rivercat and it performs excellent.

I'm about to order a few more props to try. If you guys don't mind, give me suggestions. Here's what I need them for:

32" rivercat, 2200kv 1515 castle, 6s. I'm running a x642 right now. I have an m645 is my next step up I have.... Anything in between? Maybe somewhere around a 40mm 3 blade (I like 3 blades because they don't seem to prop walk as bad)

Next is my other project I'm putting together. 26" mini rivercat (Zonda).
I was thing an x437/3 or maybe the x642 I have. Will be a 1512 1800kv castle motor on 6s

Thoughts?
