In other threads, I often find myself agreeing with the hole-haters in this thread, but I definitely don't agree here. What is it you guys want? Amigos del Mar shut down? Some kind of scuba police at the blue hole? Maybe quiz divers about their experience level at their local quarries to make sure they're not going to be in over their heads?
Seriously, what do you guys think should be changed in order to remedy the apparently horrible situation at the blue hole?
Divers are responsible for their own safety. Dive ops are responsible for providing the infrastructure (clean air, safe boat, etc.) and information (site briefing, accurate Q&A) necessary to let divers look out for their own safety. I can't speak for any of the other dive ops serving the blue hole, but this is exactly what Amigos del Mar does. Before I signed up for the blue hole trip, they answered all of my questions (and I had a lot of them) honestly and accurately to enable me and my buddy to decide whether to go and to plan our dive.
I don't have a lot of sympathy for people who are too dumb to look out for their own best interests.
It is probably in the interest of most dive ops to act, to one degree or another, as scuba police anyway. If they don't, they are likely to have constant CF dives and irritate cusomers. Or, worse, end up with dead customers. ADM does this to some degree. They give a very detailed and sobering dive briefing. They send an inordinate number of DMs down with the dive group (I think we had something like 1 DM for every 3 divers). They hang a few tanks and some weights at 20 feet, just in case. They had a very competent and professional staff looking out for everyone's safety as best they (or anyone) could. These are all things I don't expect the dive op to do, though I think it reflects well on them that they care enough to do it.
A lot of people want to dive the blue hole when in Belize. As long as this is true (at least until the International Federation of Scuba Police is formed), there will be ops willing to take people there. This is not a bad thing in my book and, based on my experience with Amigos del Mar, I think they do an very good job of meeting this need in the safest way possible.
As for the dive itself, it is possible to have a great dive without going beyond 130' (as I did). It is also possible to have a great dive without entering any overhead environment (as I did).
Are there safer ways to do a dive to 130'? Absolutely - adding more gas and some redundancy would make it safer.
Are you crazy to make this dive with an AL80? I don't think so.
I did this dive as a fairly new diver with pretty average air consumption and returned to the boat with well over 1000 psi. Barring a catestrophic (and very rare) event, I don't think it's crazy for anyone with a cool head, reasonable air consumption and good buoyancy skills to do the dive. You are welcome to disagree with me and welcome to dive (or not dive) the site in whatever manner you wish. What you are not welcome to tell me is that I can't decide for myself whether this is a safe dive and a reasonable plan, which is what I think you guys are trying to do.
