Trying to give this a whirl, but it sure is a challenge (hell, it's in the name!! lol). I'm never very consistent to begin with but on this narrow track I can't stay off the walls. I started with a Mini96 but expanded it so that I can run three tiles wide and adjusting down is taking a minute. I can hit a fast lap here or there but just can't go very long without some clunkers destroying my rhythm. Not ready to post a time yet but trying to get some laps in, maybe in the next two nights.
