When you say you want more, more what?
The MM is a grip monster, it is in a different league to a Minion, which is better than a Butcher IMO. The Minion & Butcher are better on hardpack though. The MM needs something to bite into.
The Shorty may be worth a go, but it doesn’t have the grip of a MM, not even close. I chop and change between them regularly. When it’s muddy thouh, the Shorty wins hands down. It’s smaller, and taller as someone else said and clears the mud a whole lot better than the MM.
The only downside, still to Schwalbe is the laughably crap life of them. 3 days riding in Canada, of which maybe one full day in the bike park, all the side knobs on the MM are cracking, and starting to tear, as are the same on the Rock Razor on the back.
