I had a 34 NA2 with luftkappe and a 34 evol at the same time. Luftkappe definitely better but evol is a big improvement over NA2.
Now I have a lyrik with an ACS3 and the same 34 evol.
I could get the luftkappe to sag under the weight of the bike, however coil wins for breakaway force provided there is minimal pre load in the real world. Coil is heavier and more expensive as a retrofit. Either way, a serviced fork and a damper with lots of adjustment helps, just to make the whole process more expensive.
It then leads to the discussion of cool vs air for overall performance not just breakaway force
