I've always used TF although the quality isn't what it once was.

I almost got gateways, but instead went with full length tf, and I cut 2 feathers out of each full length one, some of the quills get thin on the second feather but most of the time they are fine, makes them not so expensive anymore!

I got some AMG's about 2 weeks ago and a few more this week.  They are more consistent and thinner base than the GW's, but not as thin as the TF.  I looked at some TF's at Kzoo this last weekend.  Those are some nice looking bases.  For the price I think AMG will do fine.
