bajas are a great tyre
they offer great grip in the muddy stuff (not special track levels but still bloody good) and yet they are quite good on road. not too loud, doesnt lose too much of its handling, and the mpg doesnt drop too badly
biggest downside is width, not great in the tightest of rutted lanes
i think they are great, only need to ask booger which tyre gets you further. about 18 months back his 90 on kumhos was struggling and getting stuck where my 110 was going through with ease
speak to booger bout em, he has seen them in action. and redwings, who said something like "cant remember the amount of times you got recovered by carpy, he looked like a bendy bus 110" about a trip with beaker.
to conclude - kumhos are ok. they are not in my opinion as good as a bf mud terrain, but their road characteristics are quite good.
bajas are great. they have downsides, but if you can splash out on them its worth it. they are a very good product, they wear well in road conditions, dont behave too badly on road for an aggressive tyre, they look the dogs bollocks, and they are admirable offroad - not sensational but not a million miles off from the special tack style tyre
