I this is true. I do like magne traction, I just think that it is to extreme. There is no doubt it helps with griping ice, I just feel it helps too much. It cuts like a serated knife. It is real agressive, down and dirty. It works well but not for that perfect semi-circle lightning speed pencil line carve. I think it is best suited for what it was designed origanally for. It gives you some extra grip when you dull your edges on a park board.
A mag board will carve a turn very well. It just isn't the perfect pencil line very few people are capable of anyway. True carving is starting to disapear. You will have fun on a mag board for sure. It seems like a great quiver killer, just not an alpine racer. Like a jack of all trades, master of none. But don't get me wrong. You can carve a mag board, and it will bite very well.
