Which Axles for a 99 GT? Get c-clip elims? Who has best prices?

I'm looking to upgrade my stock axles on my '99 GT. I've got a 28 spline Eaton posi installed (pls. don't ask why 28). I'm considering Strange, Moser, and Superior brands and want to know who makes the best product at a reasonable price for a daily driven stang w/ a little more oommph. I'll stay at 28spline but should I consider c-clip eliminators? What else?

Thanks gents!
