I am getting is, "but your a new diver, you need to just listen {to us}".........yeah, Ok, I've been listening.....for about 5 pages now and I am still not hearing a single viable advantage over an octo.
Hey msinc, unfortunately, "you are new and I have a lot of dives logged, so you should take my word for it" is a fact of life around here. No point in getting wound up about it. It happens.
As far as *I* am concerned, you are exactly correct that the only advantage of an Air2 is one less hose. An advantage of debatable value. But, as you are seeing, you are not likely to change the mind of anyone who thinks that advantage overbalances the various disadvantages.
My most friendly and sincere suggestion is to be content with the knowledge you have gained (about the pros and cons of an Air2 - or perhaps, what different people THINK are the pros and cons) and put aside tilting at windmills. You know what you know and you are unlikely to even get a thank you for trying to change anyone else's mind.
I say this fully recognizing that it is advice I would have done very well to heed, myself, many times in the past.
And, welcome to SB and to diving!
