you don't have to worry about whether it's balanced or not
... I think the unbalanced ones are already extinct .... most
regs are actually OVER-balanced now ....
you don't really have to worry about cold water diving either,
in north america, most cold water diving are done with DIN first
stages, where we are, A-clamps are all that you'll see (different
tank pressures)....
and don't get those swivels between the hose and the regs
installed, that's another failure point ...
neways the new season for the malaysian east coast is starting
soon, scheduled trips are starting within a couple of weeks, it'll
be a good time to borrow your kaki's regs and see if you like them,
before buying your own ... I tried out many different brands from
friends before swinging for my regs ... you should also ...
