Extendair: any deterrent beyond cost? BOB +1?

[Danseur]

If your unit takes cartridges, is there any reason besides cost (or availability) NOT to dive them?

More flood tolerant?
Great (best?) WOB?
Same or better RT?

And in a BOB config, wouldn't the flood tolerance and guaranteed "packability" be major priorities?

**likely sidekick purchase imminent**

Thanks in advance!

I'd say your first sentence sums up why they aren't popular... that's been enough for most of us to pass on them.

If your unit takes cartridges...

This ^ is the other issue.

The vast majority of units are Not compatible- even if you could fit one in, unless the loop flow has been designed specifically for bog-rolls you will get substandard (or dangerous) performance.

Not to mention- Availability (or lack of), difficulty of transport and fragility before you get to the price.

if it takes them no.
