I plan to buy a bow soon and have pretty well decided on the Hoyt line. I' ll probably go through Ebay to find a bargain. Although I' m pretty much set on a Hoyt I' m a little confused as to which models are their top of the line after the Razortec. There are several on Ebay now that I' m considering such as Cybertec, Powertec, Vortec, Ultratec and Magnatec. I' m a left handed shooter which limits the selection somewhat. I have a 31" draw length and would want a 60 - 70 lb draw weight. Any help as to which of the above models are the best would be appreciated.
