I also purchased their top of the line Mach6 target bow and had them custom fit their Mach5 carbon limbs to the Mach6 riser since they did not offer their Mach5 target bow in a left hand model and the custom fitted bow yielded arrow speeds around 300 fps if I am not mistaken. With heavy weight hunting arrows that weighed 562 grains, the bow would send an arrow at around 235 feet per second which was plenty fast at the time. With the success with that bow, I quickly became a PSE fan and shot nothing but PSE equipment and later in 1994 purchased their top of the line aka Flagship bow, the Mach6 and purchased a lifetime warranty for the bow which covered everything except maybe the bow string.
Of course that arrow speed is nothing compared to the blistering IMO arrow speeds today of around 315 fps and more. I added a custom built overdraw onto the riser and used a Barners drop away rest and very light 1713 Easton Aluminum arrows tipped with a cut down nibb field point that rendered arrow speeds of 172 feet per second which was extremely fast for 1985. PSE Mach6 I have owned Precision Shooting Equipment since around 1985 having won many Archery tournaments with one of their round wheel 48 inch length long axle to axle compound bows.
