Thanks westkyhunter. That's what I wanted to hear. I've been shooting the same four 5" shield setup for a while with no issue, but I switched from a recurve to a longbow with about a 1 1/2" shorter brace height this year and I'm seeing the little kick mentioned with the longbow but I didn't see it with the recurve. I hadn't considered it before, but if the fletch length affected yours, it may be the brace height doing the same thing to me. Either way, I seem to have found the answer. I had 10 arrows already fletches with four 5" shields and tried the two with two 5" shields, so 12 total the same spine/length. I went ahead and stripped two feathers off of four, so now I have six of each. I'm gonna leave half of them with four because I have a recurve tuned with the same arrows that shoots great with the 4 fletch. This way I have six matches to each bow. I used glue with mine, so it wasn't as easy to remove. I left a little glue residue on so I wouldn't have to mess up my painted cresting completely. Doesn't look great, but it'll still kill a dear.
