We carry the AMG's, I love 'em. All I've used since we got them. The colors are brilliant, the cuts and quills very good and durability is good too.
JRW, I think Sagittarius produces their own feathers, I don't believe they're AMG's.
We carry 5" shields, AMG doesn't make a 4" shield unless they are a new item for 2010 I don't know about. They also make a real good camo feather that looks more natural, much like a barred but they won't make them in the 5" shield no matter how much I beg.
