I also liked the ETA on my Marzocchis. I didn’t use it that often, but it did help on steep technical climbs.
I’m running a pair of RS Revelations with Dual Position on them at the moment. DP allows you to take about 20mm off the travel in the same manner as the ETA. The forks remain active and very pleasant to ride, just shorter. The DP switch is a dial on top of the left hand leg, pretty much the same as the ETA dial. I can’t be doing with handlebar mounted levery things.
The only catch I can see is that I’d ideally like to drop them down 15mm to 125mm travel (I’m using them on a Five, and 140mm is overkill in the Surrey Hills – for my sort of riding, anyway). I can do it quite easily with a Pac Man spacer, but I’d lose the DP function.
RS with DP will likely be cheaper than DT Swiss by a good wide margin, too.
