Strange but I'm sure I replied to this topic already.
VF's in the French Alps are paid for by the community. You get the odd one where you have to pay a few Euros and they are privately leased land but its unusual to find a little man in a shed collecting money. Most just have a sign up advising you of the right equipment to use.
They are thoroughly maintained and so no worries on that score. Us local tax payers pay for that
Why would you pay £100 for a VF sling??? £50 should buy you a perfectly adequate one or better still, go to one of the sportive and hire one for a week for very little.
One tip would be, wear a helmet. VF's are about the only outdoor summer sport where you will be frowned on if your found not wearing one.
Edited to add, I've done many VF's in the Dolomites but find them very easy compared to the southern French Alps. In France you get Green (very easy and fine for children) Red (lower routes but with a few heart jerking moments to see if your ready for the next step up) Black (Usually very exposed. Often large sections of staples missing so you have to trust the rock. Certainly not for the faint hearted)
