There is a difference, I don't care what Beman says. I wieghted the two, and if there is only 8.1gr/inch, that would be a 4gr decrease. But what I weighted was a 15gr decrease. My 29.5" wieghted 380gr with 5" feathers. This new arrow weighted 365 with vains. Maybe the feathers wiegh more. Who knows.

Its not enough for me to lose sleep over. Its just a very slight tear you can barely see. I was just getting long range bad results. Like barely hitting the block at 50.
