Well I'm not sure? Someone told me that Alloy props lose efficiency when they get loaded which in turn distorts the blades, wouldn't this make the prop run at a slightly higher RPM?
Anyway, whoever is right I doubt it would make any changes to you set-up, I would go for the Alloy prop purely on the ground of cost.
