Hey Scott,
Yes, both Mike Hazel & Steve Wilk can make you good props.
I'd suggest a Dia. range of 6.5" - 6.7" and a pitch range of 5" - 5.5". So you may have to cut down that &" prop. Also, however you choose to go, the prop "load" should be aprox. equivalent to an APC 6.6D X 5P. (i.e. turn the same rpm)
Fiberglass (epoxyglass) props are more reliable & tougher IF you pit the model by catching the prop. Carbon props ultimately can be sanded thinner for the same strength & therefore can be a bit faster. Good luck & have fun!
Cheers, Paul
