RE: Hoyt Protech? Ultratec? Xtec?
Given the trajectory data that TFOX provided, as well as the lengths you're looking at, my pick would be the ProTec because of the deflex geometry in the grip. In fact, I've got a ProTec but with LXPro limbs and Accuwheels, the longest, slowest version.
What I like about it. The bow is virtually impossible to torque. It's brace height gives you clearance for cold weather clothing. Altogether, it's the most accurate and 'forgiving' bow Hoyt makes. Considering how little the speed actually costs you in trajectory...
