I shoot a Drenalin now and I've been pretty happy with it. The Z7 looks like a nice bow, but calling it a speed bow as they did in the video is a bit of a stretch. I'm glad to see Mathews came out with a 7" BH Monster.
I'm not really following the Reverse Assist cable roller, but I'm not an engineer either. I just don't understand how that can make the draw feel smoother. I know he explains it, but it's not clicking for me.
Either way, Mathews will sell a lot of bows this year. They always do.
