> (In reply to pawelx) On my first ice trip (last week) I managed to lead grade 6 although a soft 6 with lots of hooks and was fairly comfortable on 5. If you are fit and can rock climb ok this seems about right. I would say all you need is a reasonable fitness for rock climbing and a confident approach to lead grade 5 in a week. It's all in the head, a positive approach will get you far.
with all due respect if it is hooked out like the routes in rjukan have been over the past month they are nothing at all like a full 5, or anywhere near a 6 anywhere else in europe. The routes like sabotorfossen are probably only 4 in current conditions as steps and hooks take off anywhere between one and two grades depending on severity.
I think leadinga 4 after a weeks ice climbing would be a solid achievement. Especially if it is not hooked as it is a different story learning to swing an axe properly and following up with your feet just in the axe holes than yarding up steep ice on massive holes for axes and feet.
Bearing this in mind from your other post I think you may have a nasty shock on your nevis VI if you have only climbed point 5 and those routes in rjukan. Although a positive approach will indeed get you far, it will also make you fall far if you bite of more than you can chew not realising how different those routes in rjukan are to a think scottish VI on the ben.
