Even though I have the new bearing in the LET idler, since the lager idler will cut the rpms just about in half I think in may be the better choice.

Roughly the circumferences are:
LET: 4.43"
Factory: 8.63"
So there is a huge difference in rpms and the belt should get a bit more bit on the SC pulley due to a better angle.
