I run a DA150 with the MTW cannisters and a fellow flier has the KS cannisters, both in CA Extra 300L's. The KS cannisters would seem to give a smoother mid-range transition. I had to program quite a big throttle curve to get the same effect. I have a DA100 on KS cannisters, again very smooth transition. Having said all that, the length of your headers can make all the difference in the world to how the cannisters act.
