I learned two things:
1. It rode much nicer with the forks wound down
2. Hardtails are shit in the Alps.
as to 1., perhaps the frame wasn't designed to be ridden with 140mm forks? as for your second finding i sentence you to being WRONG.
had both my 120mm(ish) HT and my beefy 160mm'd Alpine in the alps (not one week of lift-assisted riding, but living and working there). both have their place depending on what you are riding. on the flowy stuff i could keep up with local lads on FS using the 120mm HT, but when it got techy, rocky, steeper or a combo of all three then they lost me. on the Alpine i can keep up with – and occasionally out-run – FS on the same bits.
the HT requires less faffing. and i don't like the jacking, bob and floaty feeling you get with FS.
ride a LT-HT with a big fork well and you don't need FS. all suspension is afterall is a get-out clause.
