Roknjs, I do notice that minor release errors are eliminated with an elevated rest. When I played with one on a couple of different bows, I found roughly a 3% improvement in my scores for the same bows without an elevated rest if scoreing the 10 ring and smaller.
"What has happened is a few small minds in there attempt to cull out a target bow has used the rule to cull out or handicap most all of the older recurves as well in the process.I shoot off the shelf to follow such rules however I will use a rest for my hunting bows.I think it is a darn shame any time a rule keeps someone from useing there hunting rig at a 3d."
Maybe it has nothing to do with "small minds" but just folks thinking they should be in a different class. Primative bows aren't expected to compete against glass etc....not sure why off the shelf should expect to compete against elevated rests.
And as far "keeping someone from using their hunting rig at 3d", no one is keeping anyone from that...at least at the shoots I've been to. If there is no class for elevated rests, you can still shoot...just not turn in your score. I've been to plenty of shoots that outlawed carbon arrows for score and I still shot my carbons because that's what I hunt with. I have also shot in those tournaments with aluminum arrows just to score in the competition. Myself and others made mulitiple, intelligently presented arguements to those that made the rules at these tournaments and some were eventually changed to include carbons. If you want to shoot an elevated rest for score, petition for a seperate class...bring enough guys with rests to show the "powers that be" you deserve your own class and voila!...everyone is happy.
As far as flat shelfed bows being eliminated, a couple of shims of leather or matchstick under a shelf plate will usually provide enough of a shelf to get good arrow flight on these types of bows.
