I didn't know that was an option, but it also makes sense. I'll add that to the list of options, i.e continue diving EAN21-40 with my twinset for a season or two and acquire further experience as I go. That can't do any harm.

Ultimately my goal remains the same: wrecks in the 55-75m range for which air is out of the question. Question is: how best to get to that point safely/efficiently and hopefully in the not too distant future (I am turning 40 next month, and although I am fit, I can't garantee that I'll still be in a position to cart around 50+Kg of kit on my back when I'm 50 - I take my hat off to all the 50+ tech divers out there, and hope to be able to do the same..)
