All the "modern day" sport routes i've been on seem to have a bolt every 2-3 meters...
I'm currently doing allot of climbing with some people just starting up in the sport and it does limit the choice of route for these guys / girls however I admit there are still are plenty of safe consumer classics....
Why are slabs in general more run out than overhung routes.... I'd rather take a whipper on a steep route than a slab.... never really understood this logic of long runouts on something your most likely to roll down as apposed to a nice clean fresh air fall on a steep route.....
I must admit it is nice when you overcome a climb, I onsighted Speed boat wankers (no big deal for most) but for me from the ground everytime i looked at this route i thought was a little under bolted, but once i got on it, i realized there were plenty of bolts when needed etc and it wasn't nearly as bad as i thought it would be....
It's "usually" the case with these type of routes (bolts when you need them) (in my experience anyways)
