Well, the real world testing of my reversed lever revealed an ergonomic shortcoming I hadn't thought of until I tried it. The position of the lever in relation to the seat is just too low and close--even with the 2" riser, it is back against my hip too far, making it awkward to use without hitting my leg when pulled inward. I need a riser on the order of 6-8" to get the hiking stick above my legs when operating the rudder from the seat. It would work fine for steering from the tramp, but I still spend a lot of time in the chair, and it has to work well there too. Oh well, this is why we try things out. Back to the drawing board....
