Hoyt never made a 2005 Powertec. Powertec is upgraded version of Hoyt's old UltraMag and Ultrasport style bows. Practically the same only with a cooler name. I would suggest looking at a 05' Hoyt Ultramag or Ultrasport. Both have great feel and are highly adjustable in finding you're comfort range. Great for hunting and indoor archery/3D.
I also agree you should wait to see the 2006 Relfex line up. I believe this is the year that Hoyt's UltraMag/Sports will hit the line up with new names.
