you are a couple of years off
the High Country carbon force extreme was discontinued in 2003
the twin Powers cam was introduced in 2003 is 65% let off and faster than the perf-X cam and is easy to keep in time especially with a good custom string.
the latest bow by HCA is the per-FX avalable in a carbon riser or aluminum IBO speeds are around 312 to 317 FPS
the advertised 350+ FPS speeds are bows using the total shooting system using speed Pro Max arrows, and Broadheads

R & D is already working on new cam and riser designs for 2005 which I am not at liberty to discuss at this time.
