Of the bows mentioned above, I picked up a mathews switchback a couple of season's ago and agree, awsome bow. I sold my previous mathew's, an Ultra-Light that I had for almost 9 years previous. I guess you can say I'm partial to the mathew's line. I use to be the guy who up-graded every other year until buying that first mathew's bow many years earlier.
I don't shoot indoor leagues any more like when I was younger and when I shot fingers. Never quite got that magical "300" but a 297 was my closest!! Since switching to a release, I was hooked at this new method to me after shooting with a tab for so long.
If and when I get the urge to up-grade again, a mathews will be the bow of choice once again, and who know's, they might have something new out over the Z-7?
