Anybody tried them and if so, what did you think?

I did. They  will give you a free sample if you call them up.

Worked fine, just looks kind of funny.

Search for it, this was brought up before and they where others that use them.

I tried them a couple of years ago and didn't care for them, didn't seem to have a very consistent grind on the quills in the batch I received.

I used them in a 4 fletch configuration on some real light carbons and they seemed to work very well out of a light weight recurve.  Give them a try.

I love them four fletch

Look at the hitman static recurve review (drewsbow) you will see them on my arrows there

work very well - i like them.  VERY quiet!!

They work well but feather height is inconsistent. Trueflight makes a 2" shield feather as well that is a little more high profile and are consistent as far as height and quality... cheaper too.

I have used them and didn't find a problem. Actually kind of like them...but can't bring myself to use them on my hunting arrows with broadheads.
