No worries, Chuck. Stick with what you like. That's one of the good things about having choices. To each his own, based on his personal experience.

No engine is perfect and they all represent a compromise to one degree or another. I don't own any OS 4-strokes, but that doesn't mean I wouldn't be willing to try one if they made one that appealed to me. For now, I'll stick with Saito and YS.
