I can only speak for the SS1.
I have the brigade with SS1. The SS1 comes with several
adapters for a variety of hose styles so nothing else is needed.
I do like it, breaths fine, and the buttons are large and easy to
locate and push. The regulator detaches from the corrogated
air hose with a quick disconnect that unscrews with no tools.
This is great for rinsing out the BC. Also it allows you to carry
your SS1 reg in your reg bag or ship it off seperately if you
want to have it serviced non-locally.
A larger than octo air Supply hose is also supplied and quick
disconnects from the SS1 as well.
The BC will inflate mighty fast with this setup. Much faster than
the standard Zeagle BC inflator. You have to use a feather touch
when adjusting bouyancy.
2 year service interval is also nice on the SS1.
As with all octo inflators, there are disadvantages.
Both the SS1 and the Air2 have a combined functionality
with the boyancy control. This means that if you get confused
and push the vent button too hard while using the regulator
it will vent into your lungs which can be bad for a variety of
reasons. You can obviously avoid this by venting with the
Reg out of your mouth - which is easy, just have to get used to it.
The Zeagle Octo+ doesn't have this issue. Neiher do the
Shadow+ or Genisis Sidekick style octo+ devices.
You definitely have to practice air sharing. Its not so bad
after practice, but its alot less obvious than it looks or would
seem to be.
One last thing not to overlook is what TSandM and Markfm said.
When you go with a fully integrated octo+ like the SS1 you
are tieing your regulator to YOUR BC because it requires modifying the BC.
This may not sound like
a bad thing but consider if your BC gets lost or more likely
delayed during your travel. You can't use your regulator setup
on a rental BC unless you replace your SS1 hose and add
a regular octo or swap our your SS1 hose and add a Shadow+
like octo.
Also, in my case, there are times where I want or have to
travel light and I want to use my regs and my hose attached
AI computer on a rental BC. In this case because I have an SS1,
I have to modify my regulator setup to accomodate a standard BC.
In my case to keep things simple, I'll probably end up buying
a shadow+ type device.
So while I really do like the octo+ concept and I really do like
the SS1, I'm not completely sure I'd buy it again over a
shadow+ type device, sinc'e I'll probably end up buying one
of those as well to deal with rental BCs.
