Has anyone got experience of L10 celect or m11/ism with a direct top and high ratio diff such as a Strato twin splitter direct top and 3.2:1 or in an Ec10 350 what was it like in comparison with the overdrive top and then the difference between a 3.9:1 or 4.1:1 diff ,did one pull away better or have more acceleration in top ,speed limiter permitting of course although you can confess 
I didn’t think an L10/M11 needed a limiter, Dan. 
I drove an M11 powered Kenworth for a while, with one trailer the gearlever knob took the brunt of the wear.
