Both are great bows. It depends on whether you shoot fingers or release. If you shoot fingers, definetly go with the V-Tech. If you shoot a release, the vipertech will be ok. Shorter bows are a little more touchy, and your mechanics have to be right on. A longer bow is more forgiving. It's a tough decision, becase the shorter length would be easier to manuever. Good luck. I hope this helps.
