I think the magna traction is pretty much BS. Keep your edges tuned well and you won't have a problem. Don't fall for it. Never Summer boards are awesome.. I love em and plan on picking one up next year.
Actually MTX works really well, way better than VarioGrip. It's a noticeable difference, so you obviously haven't tried it. But hey, don't let facts stop you.
