Given that they are all easier in walking boots than they would be in rockboots, the technical grade is essentially nil. However, they can be strenuous, especially if you have no rock climbing technique and ignore footholds.
Agree with all this. If you know how to move on steep ground (I.e. have basic climbing skills), they don't seem to get very technically challenging. If you're a hiker who doesn't climb at all, you might struggle. I was stuck behind a bunch of German people on VF Ski Club 18, which is a moderately hard "sport" VF, and some of the were obviously finding it tough going. I was waiting around until they'd gone on some distance and then repeatedly catching them up, powering through the stuff they'd found difficult simply because they didn't know how to lay back.
> So, no, there is simply no cross-over between grades since the difficulty of easy rock climbs is never because of strenuosity, always 'technicality' (i.e. not having massive jugs, maybe cracks or unpositive holds instead). Whereas the converse is true for VF - which makes them absolutely brilliant fun for the non-climber with a head for heights and some strength in the arms.
I find them absolutely brilliant fun as a climber, to be honest. If you're expecting a free-climbing experience, you probably won't get much enjoyment out of it, but a good workout on seriously high walls in fantastic terrain at speeds you could only dream about if you were doing it as a pitched climb? What's not to like?
