I use a Bearpaw feather chopper which was designed to be similar to a Vario Clipper, which doesn't seem to be available anymore. It makes a very precise cut, but requires a certain thickness of quill to work properly. Tru-flight quills fit, but the one pack of Gateway feathers I tried had quills that were ground too thick to fit. My only complaint about Tru-flight feathers is that many of them are too short to get two 4” fletches from. I remember when they announced that they were sorry, but due to the lack of availability of suitable feathers, they were going to start mixing in shorter ones. Well, at least they announced it in advance, and didn't try to slip it by us.
