3" was just an eyeball number to run the ee out to the end of the board. Anywhere between 163 and 168 would float my boat. The difference in turn radius would be negligible in a slow initiating, fast finishing ice sled. But conditions considered, you yoopers suffer vertical, but make up for it in more width AND you have pastys. We get the elevation, but turning real estate is often at a premium. No pastys at Stratton. Yeah, so maybe shorter might be suit me better, but I'd be fine 167ish.
