K2 or special track

Hi, looking for some new tyres for my D1 it’s currently got insa turbo desert tracks 245/70/16 and I’m looking for a slighty more aggressive tyre. I’ve looked into prices on the K2 mud tracks and the special tracks and think they look pretty good. Does anyone have experience with any of them or know which is better, also could do with knowing a bigger tyre size. Not bothered about how it drives after.
