I've heard of Black Swan, but have no experience with them, nor do I know anybody that owns one.
Looks like they're a high tech style of bow with non-wood riser. Any particular reason you're considering a Black Swan?
If you're just getting to traditional bows, there's plenty of very good USED bows for sale. Feel free to PM me if you want to talk stickbows, I'll try to help any way I can.
