Feel like going August 23-30, 2008? I'm going with a couple of OC recreationals and thus wouldn't mind a CC buddy or two. We're on Thorfinn.
They have Sodalime 4-8 on board and a tub of Sofnolime 8-12 (with my name on it). It's at a bit of a premium ($200 & $225us respectively) but after I looked at shipping or packing sorb in overweight luggage it wasn't so far out of line. They can get more from Guam if they know in advance. I believe they also have a supply of 3L steel tanks (12 rings a bell) with DIN valves, though I'm going to confirm that in the near future, or just take my own valves. Boosted O2 is available. Haven't asked about Helium.
From what I've heard they'll leave you to your own devices and I like the idea of going to a wreck with just a few ppl versus a whole boatload. Granted I've heard the boat has it's quirks
but I'm willing to give it a shot if I can avoid the cattle approach of Oddessy.
We're flying out of Seattle thru HNL and then on Continental's Island hopper to Truk. Northwest's and Continental's baggage policy seems to fit in with carrying a Meg onboard without too much hassle, though as of May 15 domestic checked baggage has been reduced to one free bag with the second bag costing $25 and the third bag $100.
That's about the limit of my knowledge at this point. If you're going after August I'll post more specifics.
