Jens...i completely disagree w/ you...index is no stiffer than seneca, jtree, the gunks, t-wall, stone mountain or any well established area or yosemite...of course if you want to compare it to a joke rating system like one at Owens, or Jacks or Exit 38 its gonna seem stiff...BUT, the key is those areas are off, for whatever reason...
it has its "quirks" about itsclimbing...but being local, you gain an appreciation and an ability to handle them...
The main thing is that index should keep consistent w/in its own rating scale...ie one 5.10a index climb should feel like another 5.10a index climb...and screw the rest of the climbing areas...
People learn to climb in a gym and then think they are all bad ass and don't realize that stuff can be technical, yet still not rated 5.12...Funny thing, when you work the routes at index and send them, they don't feel all that bad...they are technique, not strength based...
Long live the "index .11b"!!!!!!!!!!!
