Choosing a filter for your Synthetic Oil

Alright, so the "Synthetic Oil" thread saga seems to be drawing to a close. One thing that I didn't see mentioned much, which I believe is equally important, is choosing a filter!

So whether you use Amsoil, Castrol GTX, Motorcraft, or Pennzoil which filter do you use?

Also how do you believe the "extended protection/life" filters with the slow release additives and detergents affect your synthetic oils?

Cheers!
