I would say though that a light canister is not the ideal ditchable weight. You have to undo your harness to get it off, and of course it's worth much more than it's weight in lead. To me it's only used as ditchable weight because you're already carrying it. Better surely to use cheap weights for this purpose if you have the choice.
Hi Toby,
I think just the opposite. In many years of diving you will probably never ever need to detach the ballast. Even using a proper rigged double 15, in case of a wing crack at the middle of the dive with a dry suit you would not need to detach.
Even needing to detach, the work involved would be the same than detaching a belt... even in that case, you can pass it to your buddy and save it.
If you go for the Salvo umbilical, can open the canister, drop the contaminant battery and save the lamp and the can
