I shot the FredBear Truth. I haven't shot the Drenalin or the Vetrix but I did shoot a Switchback and a Trykon. They're all really nice. I'm going with Fred Bear but I haven't decided if it will be the Truth or the Code. I chose Fred Bear simply because, personally, I can't tell enough difference among all of them to justify paying $300 more. JMHO. Good luck!
