lol, Several have tried the MM on my local outdoor track and although it can "work", it is a far cry from ideal or easy to drive. When the MM is good, they love it. When traction drops half way into the heat, they are hating their lives. We can litterally go from pulling wheelies to spinning out over a 6 minute heat if its windy. The wind pulls the water right out of the track. From my personal experience, you can make the MM work in more places IF you at least have fairly consistent traction. When you have drastic changes in traction during the race, MM is crap IMO. That has been my experience.
