I've run it front+back, but the 48A durometer doesn't last that long on the back, so I've taken to pairing it with a Terrene Chunk Tough in the back, which is still aggressive but much harder rubber.
I think a Dirt Wizard front SE4 rear would be a really good combo. I haven't tried one because they only do 2.8 in 27.5, and provided they have a supportive casing, I like 3.0s. But I've felt the casing on the SE4s and they do seem right up my alley.
Regardless, I think the 60tpi dirt wizard is basically what you're hoping for in the SE5, and with QBP coming to Canada next year, they might even become easily available here.
