You can go to www.winnerschoicestrings.com and contact them through the website.As far as the Mity Might and Extreme Solo,If your going to hunt with this bow,I would go with the Mity Mite,its shorter then the Extreme Solo and seems to shoot smoother(I.M.O.)Bowtech doesn't make the Extreme Solo anymore,they replaced it with the Extreme VFT this year,I havn't seen one of these yet,but Bowtech is looking for the Extreme VFT to be one of there big sellers this year.Either way,your buying one of the best bows on the market.
