It's odd, small sample size, but I've recently gotten a pre-cut sheet from a local shop and it was pretty standard super grippy MOB. A little later I got a deck ordered from the other side of the country that came with a sheet that was cut from a roll. It was less grippy than normal, finer grit, and has a kind of lengthwise stripe pattern in it in the right light. I then went and got a couple more sheets cut from a roll at a different local shop, and they're also less gritty, finer grit and have the faint stripes. It's definitely milder than standard MOB.
I've only gripped one deck with it and so far it seems good enough?
I guess if you like rip-yer-face-off style MOB, buy pre-cut or check the shop roll before they cut it?
