Mine was fitted under the crossbar between the tillers. One end on the hill side and the other under the bar. It meant the pilot was twice as far from the pivot it should have been (800mm v 400mm??). Other than slower reactions, not too much of an issue. I did find the ST2000 was much faster than the ST1000, which helped. The cats dont need much movement of the tiller, they track well as it is, and at pace, you dont move the tiller anywhere near as much as a mono.
