    Takes a lot of steel. My 15x300 was more than 24kg. No fun.

    Now, 10 and - perhaps - 12L 300 bar is rather nice, if you're willing to live with the disadvantages. There are a few, but for me the advantages outweigh the disadvantages

    I really don't know what I am talking about. Seems each side of the pond have their own terminology for tanks and they don't always accurately reflect the actually sizes enough to simply use conversions. lol
    That being said, a lot of the guys around here use either the FX100DVB or the FX120DVB. The FX100 is the same dimensions as an aluminum tank. The FX120 is quite a bit longer. In fact it is even longer than my 133's. I like my 133's because they are not really that much bigger, 2 inches longer and 3/4 inch greater diameter. They may weigh 10 lbs more but I lost 7 lbs of lead switching.

    That’s really interesting: when you say they weight 10lbs more is that when they are full ?

    The physics is the same, no matter which side of the pond you hail from

    That would actually be empty. The 133 holds about 4 lbs more air so still no that much heavier.

    I dive both 12 and 15L tanks with the same weight. Once in the water its hard to tell the difference.

    Why? It IS not an optimal single tank to dive if you’re in normal or average height parameters. I never said it’s un-diveable. 12 L 232 bar is generally much more comfortable for most people.

    Honestly, I think Scubaboard is a toxic community sometimes. I don’t really care, but why am I being told all my comments are camel dung? I forgot to say 232 bar because that’s the most common pressure where I am.

    I wouldn't have used the phrase "camel dung" but your comments are often sweeping statements, based solely on your experience and training and dive location.

    It's a big world out there. Off the top of my head I could give 5 reasons why BM doubles aren't ideal where I dive, and 12L x 232 Steels wouldn't be the best for me. But reasons I would chose a certain config or indeed dismiss a config don't necessarily apply to others. There is no way @Storker kit config would be suitable where I dive, and my setup would be wholly unacceptable for him.

    So you could help yourself if your replies were more considered and you accepted that often there are other ways to skin a cat and to settle on a certain configuration one needs to weigh up all the pro's and cons that are applicable to them and their conditions. If you feel you're point of view has legs, then discuss it in a reasoned fashion rather than than throwing unsubstantiated one liners out there which make you look like a troll.

    It’s because you word your replies like if they were absolute truth: they may or may not be but this will usually not being the best of the person you talk to :)
