Is it worth the extra $ to go w/ the Tri-Armor moly/graphite coated bearing over the Tri-Metal no moly/graphite coating? Tri-Metal bearings are already an upgrade over stock bi-metal bearings. The moly/graphite coated bearings are expensive. Anyone have experience w/ the Tri-Armor (coated) bearings? I realize that moly/graphite are excellent friction reducers, but, for how long? The coating has to get removed within a few thousand miles, right? Please comment.

 

Hmmm... I'll try this in the advanced section.
