We've sold a lot of both, and all the feedback we are getting is very positive. The Monster is wound a bit tighter, so string stops (Dead End or STS) are a must. Transition into the wall is a bit more pronounced with the Monster, but hasn't seemed to cause anyone any issues. The Reezen really speaks for itself. Awesome rig! Very quite, super fast, and downright dead in your hand. Stop by the shop and we'll let you shoot a couple and you can decide for yourself. We are The Archery Den and are off exit 61 right beside the Williamson Co Ag Center. 6155676243
