Just a quick note of thanks to Jim Cobb for explaining why aluminum tanks are a Good Thing when wetsuit diving. Once explained, its all become quite clear. This is exactly the sort of posting I like to see in techdiver. Less argumentative and explaining the facts in a clear manner so that the writer is *obviously* right. I was wondering what all the fuss was about and was annoyed that I should have been able to figure it out but couldn't spot it. Knowing that wetsuits were involved was the key addition. Curiously, we don't tend to have this so much in UK diving. In the North Sea the use of wetsuits is pretty much prohibitively cold except in the case of 8mm or greater thickness (I have a friend who uses 14mm). These thicker suits have the obvious buoyancy and that means you must have a weight belt that you can ditch to gain emergency buoyancy. Having said which, if you have any sort of deco obligation then dumping your weight belt is an extreme measure. I always dive with at least two controllable buoyancy sources (dry suit and BCD) with two different air sources (currently main air supply and emergency bottle a.k.a. `suicide bottle' switching to twin 7s with Scubapro isolator manifold, b.c.d. on one first stage, suit on the other). As you can tell I've been following a lot of the WKPP ideas. They have a *LOT* of ideas that are well worth listening to and whilst not all of them are applicable to my sort of diving a significant number of the *are* and listening to the WKPP, George and Jim has helped me shake down the ideas of what I want. Having said that, I am getting some of the infamous bondage wings, but I intend to carefully check out just how tight the bondage is. We'll see how it goes. The diving I do is *nowhere* near the level of the WKPP do I'm not being quite as extreme. Right, that's enough from me.
