Could you do those chipped routes now (sans-chips)

You never know. It is a good reason not to do it. 10 years ago more or less all climbers chipped holds. I don't know any climber who has not arranged, cleaned or chipped one hold. Now I know when you chip you close a problem for future generations. It is not good for the future of bouldering, if you want to be better you have to except to wait. Sometimes a route or a problem is possible for one guy and then someone else chips the route. This has been the problem with a lot of problems especially in Switzerland, Dreamtime for example. That is really a shame, when you chip one hold and you know that it is possible for other guys that is a real shame. You are not in a good balance with your conscience.
