In reply to R Spisser:
A very good point you’re making and one I find very interesting...I can only offer my personal thoughts which are unqualified.
Trad climbing involves much more than technical climbing ability, it’s my guess that climbers coming from indoor walls frequently are shocked by how hard it can be to place and more importantly TRUST their gear.
There are many things to consider but everyone should have a grasp of potential load direction, correct position of gear (cams especially) and possibly the most important the rock you’ve put them in.
The question of how much experience a new climber needs before he/she push's the grade should basically come down to safety again. If a keen as mustard indoor wall climber breezes through (say HS4a trad) but the belayer is always having kittens because the gear he/she places is rubbish/deadly...then its not the grade they need to progress.
The anxious climber who's pro and actual climbing ability at HS4a are safe and proficient respectively, might want to up it a touch...you can mention this once but the words push and shove shouldn’t come into it.
How many VS make a VS leader??
Almost impossible to answer... VS leader of what, where at what altitude and on what rock type???
On Peak grit I would consider myself a VS leader done more than 30 of them loads at 4c and done a few HVS5a. That’s about were it ends let me give you an example. Went to Pembroke for the first time recently steep limestone a lot longer than iam used oh and err the sea lapping at the belay, I did climb VS but did I feel like a VS leader...more like VS learner. Multipitch on a long route at height altitude after a long walk in/climb on a rock type your not used to...iam sure you get the picture.
If you can easily on sight 5b/c at the wall, should you automatically get on HVS/E1 outside?
Again the equation you’re using from the wall is only taking into account one element of trad climbing, that of technical climbing ability.
An example would be someone doing 5b/c at the wall and then putting them on Cenotaph Corner, someone doing VDiff equivalent and putting them on spiral stairs/the wrinkle, its going to end in tears.
Should you get on the multi-pitches until you can prussik / escape the system?
I suspect many people myself included do MP routes and do know how to prussik, but how many can safely and effectively escape the system??
More importantly what do you do once free of the system, this may help Self-Rescue. David J.Fasulo ISBN 0934641978
I hope this of some use to you, as I say it’s unqualified just my personal thoughts on a very interesting topic.
With safe practise (and barring really shitty luck) we have a life time’s practise to improve grades technique, gear placements, mental strength, rope work, route finding etc etc etc. when you fall of and your gear rips you might not.
