Mathews SBXT for me.

But of that list I would choose the Dreny and then Fred Bear.

Guardian is top heavy and the Vectrix....well...I won't give my opinion on that one.

I have never had the opportunity to shoot a Ross.

Switchback is outstanding though

I shot the Guardian, Vectrix, and Truth and have to say hands down, the Vectrix is my choice. I have yet to shoot the Ice...

I shot the Vectrix and Drenlin the other day... I like the feel of the Mathews in my hand more, but really like how smooth the Vectrix is.
I still like my Switchback XT the best...

When I went shopping for a new bow to replace my Martin Lynx (a good bow for its day) I had my eye on 3 bows: Bowtech Guardian, Matthews Drenalin, and Diamond Black Ice. A year earlierI had tried a Diamond and was beside myself after shooting it. That really made an impression on me for I just picked it up and made a bullseye at 30 yds. first shot and had not ever touched one of these. When I tried these three out I thought the guardian was quieter than the matthews, and the diamond was louder than the othertwo BUT I shot better with it so I bought it. It's lighter than the other two and I think it's a keen little bow that should last me toretirement if that day ever comes.
