In reply to keith-ratcliffe:
There are different climbing styles and each has its own rules. For a free ascent the rules include no pulling or resting on gear. For a redpoint style you have to clip all the gear from bottom to top and if you fall you have pull the rope and start again.
I consider climbing is a sport but its just a rather anarchic one compared to most sports and competition is indirect and more with oneself.
> if a climb was originally climbed with aid but later freed then it is considered poor style/unethical to repeat it with the original aid
Well not necessarily. The vast number of ascents of the Nose are going to include some aid despite the fact it was free climbed 20 years ago. The key thing is to not claim you've done something you haven't: claim you've climbed it free when you pulled or rested on some gear for instance.
I certainly agree with applauding TC and KJ though. A truly outstanding achievement.
