fairing/prop repitch

getting ready to fly from az up west coast to victoria (stopping along the way) over to yellowstone and then home via rushmore and colorado... though still tennative.

I have wanted to add speed etc for a long time, but it seems if I am going to now is as good a time as any.

A couple of questions:
1.) has anyone tried robin (laminar flow)'s front fixed fairing? He says it is for a 6" front wheel (my 77 warrior has a 5" batman pant) but can be reshaped pretty easily with a heat gun... is it worth trying?
2.) looking at repitch... I can over-run redline @ cruise by quite a bit (even in excess of 12k feet in az). I believe I am at a stock 58" pitch. What theoretically can I expect from 60"? (gain in cruise/loss in climb though I'm working to combat drag simultaniously).

if I am gaining 2"@ 2650rpm does that yield a theoretical 5.019mph gain? obviously not exactly due to a coefficient of drag etc... otherwise my 58" prop would yield in excess of 146mph but is 4 knots a reasonable expectation? Or more over 2 knots per inch? Any math guru's out there? (Jim?)
