RE: MATHEWS VRS BOWTECH
Wrong place to ask. Lots of Bowtech shooters, not many Mathews shooters... I shoot an LX, and love it. I have never shot a Bowtech, so I have nothing to say about them. They look nice, and here a lot about them from guys on here, but other than that, nobody around here sells them.
I don't think dual cam bows are better, as was previously stated, they might be faster, but there is nothing better than a single cam bow. I think if I bought a Bowtech it would be an Liberty. The Outback is a fine bow, I like the new Switchback better though.
Overall, its all up to you, and whatever decision you make won't hurt you because both are good bows.
