If you are buying new equipment then it makes no difference. When you buy a tank you also buy a valve. It only counts if you have a pile of older equipment AND you want to interchange frequently. If you've purchased any steel tanks in the last few years the Genesis or HP tanks were about your only option. Once you have a few tanks and values with the 5/8" neck you must consider this factor when buying added equipment if you want to protect your investment > they only hold 120 at 3500 psi > (rather than 160 like the pressed steel or faber), The only way to get 160 into these tanks is to OVERFILL them. We are talking about low pressure tanks right. These are rated at less than 3000 psi. It is not safe to put 3500 psi in a 2850 psi tank. > and they have the wrong buoyancy (neutral when empty), meaning you > must weight them to rpevent floating in a low-on-gas emergency. The Genesis 100s are neutral when empty. The Genesis 120s are only 1 lb positive when empty. BFD. You'd have to let your air supply get pretty low before these tanks go positive. And we are only talking about a pound or 2. An extra pound of buoyancy when you are almost out of air is not so bad is it. > Like most things in recreational diving, these tanks were designed to > fool you and confiscate your money , and leave you with worthless crap > when you could have had the real thing all along - 104's. -G Mike
