So the pinion gear teeth were then able to find their "sweet spot". This seemed to alleviate the noise, at least so it was acceptable. Still one of the noisier sets of gears I've used.

Doing this would also increase the backlash (the pinion teeth aren't sitting as deep into the bevel teeth - therefore more clearance/backlash). That's my guess as to why it was quieter after.

Do you remember what combo's you tried? Specifically, if you changed out the bevel to a non-modify gear and noticed quieter results?
Have you seen a regular ratio modify gear set installed?
What's your general experience with other brands of torque up gears?
After seeing a buddy's systema hi-speed gear set and the tooth profile of the spur gear, I've refused to use anything but regular ratio gears. They've always worked great. I've seen m120 springs pulled easily by mini batteries and if extra ROF is needed/wanted we up the voltage of the battery.
