Hello everyone, I'm looking to buy my first set of tanks in the coming months and am pretty sure I'd like a set of HP steel 119s or 120s. I dive mostly off NJ on wrecks. For the past two years I've been renting HP steel 120s from my dive shop and they have worked out OK but am thinking the 119s may be a better fit. I'm 6'0'' tall, 190 pounds and dive a Halcyon Eclipse 40 rig. I'm just not too sure of the differences between the 119s and 120s. Is the only difference that the 119 is shorter and fatter and the 120 is taller and skinner? I'm guessing there is really no difference in the volume of air each holds. I'm not looking to double them up right away but would like this to be an option in the future. I've also noticed that the 119s tend to run a tad cheaper than the 120s, any reason for this? If someone could point out some pros and cons to each I'd greatly appreciate it. Thanks in advance...
