Default March pullies?

Anyone heard anything about these? They're supposedly the same size as the ASP pulley but with a better dampner. They're also SFI certified. Just wondering if anyone has any experience with these.

Thunder was offering a special on the March pulley(see "Sponser" category).
Paul(?) at Thunder told me they were having some initial fitment difficulties with this part, and had contacted the manufacturer about same. The March pulley is the same diameter as the ASP, and offers similar HP gains.
