Dan makes a good point. As you might guess, the diving community in Boulder has a number of expert climbers in it. I am not one of them, but I have listened to some real expert climbers talk about it during long road trips. The best climbers know the best climbing techniques for all situations, and when they are doing the hairiest climbs, they are using those best techniques.
In this case, you are talking about excellent recreational divers who used none of the best techniques used for diving beyond recreational limits.
