I love the ETA for climbs. not only does it lower the fork and stiffen it , it also still gives about an inch of travel for those rooty technical climbs.
a good pipecutter, a mallet and a way to install the star nut are all you need to install it. I used a dowel rod and marked the old star nut height on it and bopped it in with the mallet to the mark. the only place you can really flub up is cutting the tube too short or crooked and if you bang the star nut in too far they are about a buck so just get another one( I always buy 2 instead of just 1 to have a spare)
