This is so confusing because I get a bundle of diffrent answers.
I'll get 13x6, 13x8,14x6,14x8 and make up my own mind.

I thought there were some general rules/preferences, but everybody seem to have their own theory on prop-sizes..

One question though:abacro How can both the .70 & .91 have the same "best overall prop"??
It just doesn't make sence, then it's no reason why I should pay another $50 for the .91 if it swings the same prop as the .70??
