Both sides if your statements are completely true and that's the problem we face in the business. The nearest thing to an mb I have used is an old mtsd with the 62" sd deck. It had a 20hp kohler and would cut almost anything. Side hilling was a breeze as well as stopping and turning around. We have a good deal of Bermuda around here and it left a cut on Bermuda that was second to none. As you know, Bermuda will show a deck's weaknesses faster than anything. Of course it was not an mb, but I'm sure the mb's are an improvement over that machine.
