3 blade equivilent?
 

what 3 blade would be equivilent to a 30x10 mejzlik? I just ordered the mvvs 116, and they claim 6100 with a mejzlik 30x10 2 blade, and thats a lot of prop and motor for my new qq yak, so going to use a 3 blade to absorb the extra power, what do you suggest? I was thinking 27x12 or 28x12, not sure though.
