So from reading the thread, it is clear that most experienced divers would have "thumbed" the dive. The op and his buddy did not. It was a high stress dive, for sure, due to dark, low viz, surge and weather. A lot could have gone wrong, but didn't. Many of the risk factors on this dive related to entry and exit, and I understand that once down, the divers may have wanted to get some bottom time for their effort. I am sure each learned from the dive , and are better divers for it, in part because of their perseverance, and in part in spite of it. Having learned what they have, my guess is that if they have a repeat experience as to conditions, viz surge and weather, they will agree with the rest on this thread, and thumb the dive. Live and learn, and live to dive another day.
