I would be interested, but I can not gaurantee any dates until the week before usually.
Walter asked for comfort levels and the such, so here goes. I am comfortable 2000ft back in a cave. I love small tight restrictions. Low vis does not bother me. I am PADI, NAUI, and NSSCDS trained. Easily silted out conditions are no big deal. Deep is relative. What do you consider deep? I will dive to 130-160ft on air, but no deeper. That is trimix territory IMO.
So, if anything comes out of this, please email me with details, and i will try to make it.
