I guess there is always a “better mousetrap”, but always at the cost of
complexity and weight.
FWIW, I find the simply, factored-down, mono mechanism design, with the bungees
work absolutely fine and with minimal effort.
In fact, just like in a performance car, I very much appreciate the ability to
“feel” the forces involved, to be able to assess the mechanical and aero
performance of the system. Adding mechanical advantage by definition reduces
the feedback feel by the same advantage gained.
FWIW
Cheers,
