I'm not trying to ruffle anyone's feathers either, but I am going to say that if you think that diving a single AL 80 to 200' is a superior technique as compared to diving with redundancy, and a gas plan that includes contingeny reserves for yourself and other team members, that you may want to officially broaden your diving horizons and catch your training up to your diving. You would probably really enjoy the courses beacause you seem like a guy who's pretty dedicated to diving.
porsc, can you specifically tell us what techniques you're referring to, I'm curious about what exactly is being done. Otherwise I'm left thinking the same thing as Scubakevdm.
