My Marz has been put through the test in the past month over some tough technical single track and not a issue what so ever. In fact, my wife's coil fork has more residual oil on her stachion tubes after a ride while mine are totally clean. But they are two different companies we ride however. But I tell you, air is the way to go in my book. Just pick up a decent little fork pump. I bought a Sette from PricePoint for like $17 and it works great.
