Don't worry about whether some yayhoo thinks you're not 'trad' for using an elevated rest. They have no historic justification for that opinion. A great many shooters used elevated rests on their recurves in the 60's and 70's.

A lot of vintage bows were tillered specifically for elevated rests. They were MEANT to be used with a rest. In fact, a lot of real old timers are mystified by the craze over shooting off the shelf because they proved, long ago, that elevated rests deliver superior accuracy.

I like shooting a hunting bow off the shelf because of the simplicity, but I've shot elevated rests on many recurves. I'd recommend getting an NAP Flipperest. Just peel and stick.

I don't know how long you've been shooting recurves but here's some tips. If you already know, maybe someone else needs to hear this. If your arrows are porpoising, up and down, adjust the nockset up or down. If they're fishtailing, side to side, twist the string to raise the brace height in 1/4" steps until arrow flight cleans up. And make double sure your arrows are the proper spine.
