In reply to ConstellationLyra:
I don't believe that dry tooling will follow rock climbing in this direction, for the following reasons;
Almost all dry tooling areas are in old quarries, or areas of dubious/unsafe/usually wet rock that have been deemed to be unfit/unpleasant for trad or sport climbing.
Boulders by their nature are more solid pieces of rock, that have survived being separated from their original location. They will therefore be desirable to rock climbers/boulderers.
The current state of ethics is that dry tooling cannot take place on ANY piece of rock that can be safely climbed by rock climbing.This will exclude dry tooling from taking place on these boulders.
If a boulder is so loose that rock climbing is not possible, or unsafe, then it will probably not be a boulder.
For these reasons I feel that dry tool bouldering is almost a contradiction in terms, and is therefore unlikely to happen. Though I'm happy to be wrong.
