i quite liked the eta on my old marzocchi all mountains, more specifically i liked that the front end dropped and locked so assisted with climbing and then a lever flick brought me back to full travel, no fiddling with ride heights it was either low and locked or high and bouncy. Very very good/simple forks.
since these i have used talas 32's with lockout and found i used the lower travel settings without locking out incase a lary bit of trail came up and i didn't feel comfortable changing travel on the move, but this often led to longer descents being done in shorter travel options, which sorta defeats the point.
My current forks Rockshox dual air 150mm are a return to simples, they have a lockout which is rarely used but does have a 'blowout' should i meet the lary bit of trail again, but other than that the + and - air chambers allow the fork to ride quite nice both climbing and coming down, I'll admit i am playing with stem's now though.
