The advantage of a vertix (or newer) Mathews is you can change the draw length, draw weight and % let off by only changing the Switch weight mod.. I bought a Vertix when I started archery as an adult and initially shot it at 55 lbs with a 60lb mod then moved up to 70lbs with the 70 lb mod and have since dropped back down to 62 lbs with a 65 lb mod.. I also changed my draw length when I went from a wrist strap to a thumb release.
