FRPP 373N Gears???

Ok, thanks Ricky, but....
FRPP is making a somewhat new gear set ( M-4209-373 N for New?):

New manufacturing technology utilizes a Face Hob Process which features a single pass pinion tooth machining operation compared to a conventional three pass process for machining. CNC cut and lapped gear teeth. Higher strength and better quality gears are produced with the Face Hob Process. (Continues...)

Evidently the set I just purchased is this new N type. Soooooo, my question is more specific: Has anyone tried these -373N?

Thanks for the post. All help appreciated. :cheers:
