A first ascent gu is a different beast than an fa td and shouldn't be vulnerable to retro'ing bc it takes the climb down a notch when it was already an established success at a higher degree of difficulty. It is like saying no need to try harder lets just add some equipment... tho I've totally enjoyed some additions in this way no doubt.
Not to disagree, but isn't there a bit of value judgment embedded in that? Higher degree in what respect, commitment? I have a feeling that some who are after pure technical difficulty might argue the point, as the absence of protection 'robbed' them of the opportunity to do the route when they weren't willing to step up to the commitment required. So they would see it as lower rather than higher. Some consider the B/Y a complete waste of the resource, others see it as a lofty example. It's certainly not the technical difficulty that makes the B/Y an undertaking, it's the other things it demands of you. Depends on what you're looking for, or think is important. GU and TD are definitely different animals. One requires you to bring more tools to the table, and if you're looking for a full value experience then that's a desirable thing. But there I go, injecting my own value judgment into it...
Every climber has his definition of 'hard.' For someone 5.6 is a free solo, for someone 5.12 is a free solo. I think we can all agree that it comes down to being challenged and not getting mangled, and the line we draw is very subjective.
True.
On somewhat of a tangent - if one is putting up FA's I think it's worth considering what the afterlife of the FA is going to be, and who is really targeted. If I happen to be a .12/.13 climber is making that .10 route challenging by running it silly really the right thing to do? If I did, then the route will probably rarely be repeated, and it likely won't be done by people whose limit is the grade. And what would I have really proved? In a way all I would have done is rob people. What's not hard for me may be hard for them. I think we sometimes do a disservice if we don't look at the overall picture, there are trade offs and balances worth factoring in. On the other hand, running that .10 pitch in the middle of that .12 route is a different story - bop till ya drop if you want. New routing can get complex, can't it? There should be runout routes at all grades for those who are seeking that aspect of the experience, but it is usually the experienced climbers doing the new routes. So where to draw the lines? Subjective with lots of things to consider.
