Well the J-valve was a free gift and still in good (tested) order though I've forgotten the advice upon its use. something about I switch a valve when I get to such a bar or something. I don't mind the novelty of using old or historic diving stuff as it arouses a sense of nostalga and belonging of where i've been and where I'm going to.
Oh damn! Just remembered that I forgot to take my father-in-law to pick up a new suit from a Dive Shop. It was a 'reward' for raising the alert that the Dive Shop was losing a lot of gear and tanks to some thieves. He won't mind my forgeting as he still prefers his ratty and holy 2-peice mothball suit. I don't get a kick outta that sort of old though.
I never use a Pony Bottle until I start Solo Diving (I think I took Andy's advice upon this) so where does a Pony come into play with Twins?
I take your point about using Twins when they aren't justified upon a dive that can be done on just a single...just that I've seen a number of photos upon this Forum where people have Twin-setups in use.
What Twin-Setups do you guys use? I think 15L would be a too cumbersome Twin-setup though maybe 12L Twins might be the go for airtime and weight.
...should I just save my Pennies and put it towards a Rebreather eventually
