Depends on what you are looking for. I've been riding with a Non-CGA since I was 14, it's just what I got used to. I always make sure the people I ride with know that I don't float too well with it. I use the A-10 attack & really like it a ton. Super comfortable and you really can't tell that you're wearing anything. I'm 5'8" 145 pounds on a good day & I wear the Medium. I have some friends that are a bit larger than me & they fit into the Medium as well.
