Nice justification article Dave.
There are lots of reasons to buy new skis;
1) You only live once
2) It's only money
3) They'll make you ski better
4) It just feels good to have new stuff
and I am sure there are more.
I may regret the decision when I am slogging into or out of some cache in the High Peaks, but I just have to keep reminding myself - it's the journey.
Don't ski the trees, ski the spaces between the trees.
