If want to get off grades & wide trails suck it up on Trail 2E also grade to 15n then enter 15n to Sidnaw or 111 to Amasa from Amasa could do Republic then U turn back many miles of Twistys in there. If in Amasa you might see the lap groomer on 111 freaking guy goes faster than some sleds!! lol
Oh yeah all the way to Iron moutain never been beyond IM/ Florence on 2. IDK maybe 20 miles or so to 15 junction from WM...well worth it to spend all day in Twistys, Amasa, Republic, Crystal Falls otherwise going north you have to deal with grades & wide trails all day maybe duck in 109 but that is about it other than Greenalnd 13 loop but again small amount compared to the interior.
