You might consider the 250sf and then look for knobbies for it. Even if you had to lower it it at least you would be starting from a lower point. I am in the proccess of lowering a sf for my girlfriend. I may get the parts in this week and try and post some photos.

Yes, pictures would be good.

But they don't sell the SF in England. Soo, would have to be a grey import.
