Some vee rubber tyres are rubbish, but then they make the floaters which are quite good and the hillbillies look similar.
I’ve only ridden a fatty so that limts the usefullness of this oppinion but:
1) Needs to be longer, I went for a large at 6ft, it rides perfectly, but means I can’t fit a dropper despite the standover the seat mast is 20″.
2) Needs front suspension. Fat tires soak up roots, but do absolutely nothing to soak up bigger hits or the kind of washboard/potholed trail you get at trail centers as the surface erodes.
The Tusker solves 2 of those problems (although unless your huge the large is mahoosive and the medium is no bigger than the Fatty) and I don’t know how the steeper HA and shorter fork offset would affect things, I imagine slightly more nimble but with a similar amount of low speed flop (which is negligible).
