Have used elevated rests on my recurves for many years. Back when I started they were very popular. The biggest advantage to me is easier tuning, along with the ability to shoot vanes if the weather is bad.
It's possible to achieve good flight off the shelf but for me doing it with a rest is a little easier. They will sometimes be more tolerant of arrow spine allowing you to shoot a bigger variety of shafts.
Depending on the bow a Bear Weatherest, Hoyt Super rest, Hoyt Hunter rest, or any of the others will work fine. The one critical thing you have to be careful with is the Centershot on the bow. Sometimes a rest will be to thick and move the arrow out to far from center. As for durability I've never had one fall off in 53 years of hunting.
