So it would seem that a route TD done in harmony with the features and texture of the climb could yield good artwork. A well produced canvas and backdrop to practice the artistic movement on top of?
Yes, just my opinion. And if the original dance was done GU, no doubt it is certainly more respected - as it's unrehearsed, like improvisation. But for those who later climb a good route, the beauty of the movement working with the rock, rather than fighting it's natural features (contrivance?), can be appreciated regardless of TD or GU.
I also like susan's thought about respecting the extent of the effort put into the climb, regardless of style. That said, some new climbs come quick and easy, like a brilliant pure crack just waiting to be ascended. And others might take many falls over numerous days, and lots of drilling, and ultimately yield a route others have little interest in climbing. The Sistine Chapel took tremendous effort, and is no doubt a masterpiece. But there are other "process art" works by contemporary artists, which take countless hours to execute, but are ultimately seen as kinda lackluster by many. Andy Goldsworthy, on the other hand, is in artist who takes great effort over many hours or days to execute work with pretty broad appeal. (Excuse me for comparing this stuff to art again, but of course it's hard to resist, being both an artist and a climber.)
Ultimately, regardless of process, for the majority of folks out there (the audience, if you will), the final product still has to have some merit.
I must say I also really like the Higgin's quote you inserted, Susan. I remembered those words. By all means, lets maintain respectful discourse and a variety of climbs.
