"if im gonna be taking out the bearings to repack and clean them why not just replace them at that time?? (if its cheap-ish)...."

Define cheap-ish. I wouldn't classify rotors in the cheap-ish bin myself but it's your call. I personally wouldn't replace them until needed - but that's just me. The trade off is that you'll be doing 80% of the work needed to replace the rotors during the bearing repack. The only thing you won't be doing is pressing out the races.

Bart, I saw that link but I was on a mission for Kenny's. I may have already done a pdf of his write up. I'll see about getting it put into the How2 section. I'll have a look at this one to see if it's worth having both.
