Hi Outlaw, I am coming out for 3 days diving on the Zen on 12/13/14 October. Diving with Octopus Diving Centre as we have dived with him for the last 10 years plus. Can you let me know where I can get sofnolime for my Inspo for a sensible price? Two of us diving on inspo's so will need 15 Kgs total. All the best, Chris
