I used one this season. Last couple of years I started having shoulder issues, from an accident, so it kept me in the game. But recently, some regular stretching and strength training has returned my shoulder to proper form.
I'm a vertical recurve shooter and when I got the crossbow, the only choice was which horizontal recurve to buy. I value simplicity and resilience over most other qualities. All that being said, my next bow will probably be a reflex-deflex longbow. I've had my eye on them for years.
