There is nothing wrong with ANYBODY using a Xbow! I could care less about the guy down the ways using one!
With that said, go and shoot as many as you can get your hands on. Just like a compound, they all are a bit different. Some are loud, some are quiet. Some have lots of vibration, some have very little. But since your the one that needs it, go and shoot them!
I fired a few with Dad when he went for one. I was surprised how different they are.
