what is it about a 25' route that is different from 65' route, other than length. I think you're saying that length, by itself, is a quality of it's own in determining the value of bolts.
I don't necessarily disagree, but it seems as though there are lots of lead climbs that are short that are quite enjoyable to lead (assuming of course that leading has a lot of value for 90% of climbers). So isn't more lead climbs better?
I would say yes.
The counter to that principle of unrestrained bolting is minimum impact practices. Do we need to have lead bolts on anything less than 100' anymore? Probably not. Just TR it, right? I know, it's an age old agrument.
