I dunno, I've always used fletchtite and more recently (last 4-5 years) the Platinum with excellent results. I haven't lost a feather in..........a long, long time (so long ago that I can't even remember it). I think my last tube was bought in the spring. I always prep my carbon shafts the same way I did the aluminum - rub vigorously with Acetone on a paper towel until the shaft squeeks, then don't touch the area you want to fletch before you put your feather on. After the arrow has dried I put another drop on each end of the feather and sometimes run an extra tiny bead down the thick side of the quill again.
