Okay, I have decided that sometime soon I want to get a pony bottle. I want the security of an alternate air source. I know all the arguments for and against doing this so please, let's not go there. My question is, for those of you who have made the plunge, if you had to do it again what kind of setup would you recommend? I am a big guy 6'2" and I still don't have the greatest SAC rate so I am leaning towards a 30 bottle.
