There is another variable in the equation - you were riding at Croom in Central florida. In that terrain (lots of sand whoops and deep sugar sand) you are going to be better off with the light of the 2 stroke. That is why you see so many people in Florida on 2 strokes. The terrain here eliminates some of the benefits of the 4 stroke engine. That being the case, most motocross tracks here are hardpack and that is where you will see the 4 strokes (YZF and KTM) shine.
