Waynel, if you are going to be diving with Dive with Martin this week, tell Miguel Estrella that I said Hi. Like you, I like Dive with Martin, but primarily because of the Dive Master - Miguel is great for a relaxing dive while showing you things that you might easily miss, I've been diving for 25 years now, with several hundred dives, and though I can occasionally find a Splendid Toadfish on my own now, I'm going to miss more than I find, and a really good DM can add a lot to a dive. Indeed, if it weren't for the DM, I'd put a lot more weight on other factors. I love HP Steel tanks, and the Steel 120s provided by Aldora mean lots longer bottom times and better buoyancy characteristics - with a Steel 120, I can use 6 lbs less lead. And while DWM will provide an AL100 (for an extra charge), its just not the same, as the Aluminum tank still goes positively buoyant at 500 psi, meaning I need to take extra weight with me.. And if I want Nitrox for my second dive because of the extra safety factor, with DWM, Nitrox is only available in AL 80s, while with Aldora I can get it in any size tank I want. And I really like the long SI at a beach club offered by Aldora - long SI means longer and safer second dive. So while I like DWM, and I really enjoy diving with Miguel, if I have a choice, I'll spend more and dive Aldora.
