Recommendations for pony bottle/regulator set up for solo diving

Empty AL80 gets to be noticeable but no big deal and plus you're in the last 10 minutes of the dive then anyway.
Faffing about with both reclipping or moving the tank plus moving a weight around just isn't worth it.

Maybe my wing provides more stability than others though (Xdeep Tec)? I could see a wing which balloons being less stable.

@Tigerpaw,

Here is a link (Gas Planning Example) to an old thread that contains an example that details, among other things, how you might determine the minimum size "needed" for a pony bottle (bailout bottle) for a recreational dive.

The example is straightforward, written for a 100 fsw NDL dive. I learned to do a simpler version of this approach to dive planning when I took my open water course (in 1986). You might rework the example, but using a 130 fsw NDL, instead.
