I use 2 types ONLY. Magnus (Matt Gundock) ground natural turkey feathers (dyed just about any color you could want) OR Trueflight. Quality of each are unmatched in my book. I have tried the others, and unless they have changed the way the manufacture and their feather suppliers, I have NO interest in switching.
Now, these are just my findings, but typically when I find something I like and it works, I stick with it. In my experience, saving a few dollars ends up costing you more in the long run.
