Rear Axle Bearing?

[AmKenpo1]

I was looking for some feed back on the type of axle bearings being used by the Pro-Touring cars. Mostly I need info from folks not using a floater assembly, but I will take any information you are willing to share.
Let me know what type of bearing (Ball or Tapered) has worked well and what has failed.

Thanks for your time.
