I finally had time to call around today and have yet to talk to any shop that has heard of or experienced problems with the coated gear. It seems that as long as the 10lb / 1000 RPM rule is followed, oil gets warmed up prior to abuse, and a reasonable viscosity is used no problems would be expected. If you have 100 psi cold at 100 rpm with 20w50 and hammer it out of the shop two minutes after start up this gear is not for you. Hope this helps out.
