There seem to be at least a few ways of attaching deco bottles in sidemount: one posted in an article by Rob Neto, another demonstrated by Jeff Loflin in his DVD, some people use the same setup as with backmounted doubles, and there are probably a number of others, or their variants, that I have not seen. Which system do you use? What others have you seen in use? Why did you choose your system over others? What are the pros and cons of each? Thanks!
