I'm aboard a Guerilla Gravity Smash (140mm), running Schwalbe Magic Marys F&R.
You said you don't want a 1300g tire because you don't want it to be a slog to ride but IME the mud is a far bigger factor in "slog" than my tires are.
But I admit that I don't mind heavy tires in the off season. I'm not racing, I'm riding for fun and to keep my fitness.
A tire that offers more grip contributes to the fun and a heavy tire contributes to my fitness.
So I don't mind the Magic Marys.
I've also had good experience with Maxxis DHF & DHR.
FWIW: been riding Oregon's sloppy singletrack year 'round since '85. Good grip is paramount.
