RE: .28 in a funfactor? oh dear....
I was totally blown away by the handling of the 1/8 scale buggy wheels myself. On a high traction surface the differance is even more noticable and with the right suspension setup it will fly around corners almost as well as an onroad car.
Eventually I am going to try the XTM XLB's wheels and tires to see how they handle. They are almost the same size as the MT tires but they are still lighter.
The Schlesser looks real good with that wheel combo I might have to get one myself.
