I've owned multiples of both. They are both in the top 5 of recurve bows in terms of performance and appearance. My advise is that you need to try each and make a decision on your own. I don't own either at present or I'd let you shoot them. If you're not a member, then join the Trad. Bowhunter of Md. I'd bet that you could find a member that has one to trial. I'm not sure if either Blacktail or Schafer offers a "try before you buy program" or not? You might want to contact them and see. In the long run, you can't go wrong with either. And if you don't like it, the resell value and time to sell would be good, guaranteed.
Good luck,
Kyle
