Take more than one and test 'em. The props we get often vary so much that two of the same dia/pitch of the same brand will sometimes differ. Not usually too much, but enough to tell. Also, the altitudes at our fields make a difference too. That usually makes the most difference in what everyone gets for results.
Will do, I plan on swtiching them out during intiitial engine run in. I have a tach, so will see which on works best for RPM. I'm also curious about air flow over the wing.
