Today was just 'proof of concept': First time on my ice-blades. The ice was slightly covered with snow, which is no problem for the ice-blades. The wind was not strong enough for my 4,5m2 Ensis Score wing. I forgot my harness, so quite quickly my hands started to cramp up. And (!) the wind-chill was -30 today, which was on the chilly side: My fingers started to freeze :D.
