I used one for seven years on my recently decommissioned commuter. It required direct and applied concentration to overcome decades of riding experience to run it right, symmetry of levers' movement or not.
An interesting footnote is that the "low normal" derailleur springs pull the cage and pulleys to the biggest cog at rest. I have ha\d to replace the jockey wheels twice during its service, and I am talking about the pulleys gone wobbly and wonky, not tooth wear. I have never experienced that before. My hypothesis is that the natural and resting mode is to pull against the larger cog; force applied from the chain on the pulley wheel teeth to the lateral, stressing the bushing function and integrity. I am frankly amazed it shifted at all when I first saw and appreciated the level of debility. I'm talking upper pulley able to cant at 30° off chain line. New commuter has a normal RD. The wiring to operate that is very deep in my CNS and I can ride almost as a complete reflex, absent of any focussed thought. Perfect for the end of my 12-14 hour days riding home in the dark.
