The only Hoyt with a set draw length is the Trykon. Of course, it's also the only one with parallel limbs. Most of your other Hoyts, ie, the UltraTec, Vtec, PowerTec and such with the cam and a half have 2 1/2" of draw length adjustment. Reflex IS Hoyt, they come off of the same line, same cam system the whole deal. You just can't go wrong with either of them. Personally, I shoot an UltraTec, and my son has a Reflex Grizzly. They are both just incredible shooting bows. I can't say a thing objectively about Alpine, never seen one let alone shot one.
