Im not sure If you can still get the XL anymore, maybe they may have a few left in stock,the new lengends are called Legend HD Pro. You can get one in the 150# draw too. It shoots at 280 fps with 72 pounds of energy on impact. Just go to www.crossbow.com and you can get all of hortons info. As for the mechs you are talking about I too have the itch to try them, just have not done it yet. I am sure you can order it just give them a call.
