Just funnin. Thank ya'll for the information. As I can see, this is like many topics on the board and subject to much debate.
As far as my question goes, I am all set. I bought the tank from an LDS here in Dallas but a different LDS than I frequent. (My regular LDS did not have what I wanted in stock and I wanted to dive it the next day, so..) I bought it on Saturday to dive with on Sunday. I didn't have time to stay and have it filled, filled it at the lake the next day. Plus, the guy gave me a great deal on the tank, matched Abysmal's current sales price and as it was already about 10minutes past his closing time, I think we both were ready to get on our way.
Anyway, they put the valve on and did the visual. He explained as he put it in, real casually, that you jusr hand tighten and give it a bump. But without pressure in it yet, the valve just fealt way too loose. As I am not one to ever accept anything blindly, I decided to check his info against ya'll expertise. Which once again, has seemed to worked very well. As soon as I filled it at the lake on Sunday, it was rock solid tight. Self tightening at its finest.
Thank ya'll
Bill
