So that being said.... what gears are you guys running in your 9" that don't whine. There are a dozen manufacturers and I don't want to make that mistake.

Call Randy's Ring and Pinion.... (google 'em) and they'll know more about this than the average guy on the street (which is what you're asking here). Or call and ask Currie -- or Strange.... They all have lots and lots of experience.
