I rode a lot of Magna Traction here in Michigan. I've tried all of the male Mervin teched out boards... Rossi, Lib, and GNU. They all rode really well in Michigan ice. However, a lot of them lacked pop. I mean it wasn't bad by any means, but just noticeably less pop than compared to the likes of Ride boards. The top Mervin boards that stood out to me were:
Lib Tech: Banana Magic (Expensive, but if you do manage to see one within budget, get it! This board was absolutely a blast to ride.), Skate Banana (I think this board is overrated, but it is pretty damn decent. If you find one for cheap, I wouldn't hesitate picking it up.)
Rossi: One Magtek. All the boards I tried were 2011 so some things have changed. This one had combination rocker/camber. It was a great board to ride here in Michigan. This is a price point board which is shocking considering how much fun I had on it.
I didn't really like the GNU boards I rode. Especially the Park Pickle. I didn't notice anything outstanding about it at all.
Ride also makes great boards. If you are into regular camber, the DH is an absolute great ride. I still love regular camber boards and there will always be a place in my heart for them. The DH is a great camber board. The Machete and DH2 are also great boards. David Z here in Michigan rides the Machete.
I keep saying this next one everywhere, but the K2 Turbo Dream is a sick board. The rocker on this board is near perfect. The 2011 gets harshmellow which adds to the dampening factor for higher speeds.
