Thanks a lot guys for the input. Bart, I don't have a TSC here in Colorado but a couple stores that are similar I'll take a look there as well.
old abe - I know some really like the Blue Kevlar belts. A mower tractor I purchase a few years ago now had the Blue Kevlar belts on it - both on the front PTO and inside the deck for the secondary belt. The PO told me they were new belts and they did look pretty good on the surface. However, they quickly went to pieces. I don't think I'll be usin' any of those belts on any of my tractors. I had a bad first impression. You used the word "cheap" in your post to describe the Kevlar belts. Apparently, for me anyway, the saying "You get what you pay for" rings true once again.
I guess the reason I brought this up to the forum was because not all belts are created the same. My primary concern was the degree of bevel on an off brand (non OEM) belt matching the OEM belt. As Bart had mentioned I guess I just take the OEM belt to the store and hope I can match the width, thickness, and bevel as close as possible.
