Bows have become faster ( judging distance became less crucial). Bows are being made quieter ( more enjoyable to shoot but deer will still hear it). But did the bows become more shootable? I say no. I have owned several brands of bows, two cams, single cams, hybrid cams, magnesium riser, aluminum riser, long ATA, short ATA, and I can't say that any of them shot any better than the others. I believe the biggest improvement in my shooting came from learning proper form. Bow companies add new gadgets to increase speed or reduce decibals so they have something new each year, if they didn't change anything we would all just keep what we have.
I have an older bow that sounds like a rifle going off, but it groups arrows just as well as my newer quiet bow. So I really can't see compounds being banned just because they are a little faster and alot quieter. I think most of the advancement in archery has been in us shooters being taught proper form and techniqueby way of magazines, videos, and forums like this one. I hate to see the bows get all the credit. I think we need a little too.
