Hey marv,
Have you been raiding the scrap dealers for lead or what?
As that's one helluva V-weight you're talking about...let alone
slung on a weight belt.
How much weight do you have to carry with your twin 80's in drysuit
and ocean diving?
Just curious...

JIm,
I guess the difference lies in thinking about what one is doing. you
seem content to ignore any variables in your dive and stumble blindly
along hoping that you will have brought enuff of whatever.
i could be wrong but this seems to be the antithesis of everything these
florida guys preach.
the plain fact is i am worried about your approach and its consequences.
your recent post about brass fever was disconcerting to say the least.
you may think i am just busting your ass for the sport of it, but
frankly i am trying to help you see that there is a reason to consider
each dive as a seperate exposure and to choose equipment accordingly
with the dir principles in mind, instead of insisting on a one size fits
all approach.
I suspect that you have not even tried to experiment with smaller tanks,
which while they require weight to compensate for their buoyancy are
still less of a burden that the 104's. The fact is double 80s in a dry
suit can be made to work quite easily and the result is a smaller
cleaner rig that handles better overall, whether scootering or swimming.
160 cu ft of gas is sufficient for a single dive and you can get two
sets of 80s for the price of one of 104's. a v weight can easly be used
in place of a weight belt for those who would rathernot be bothered,
although this does preclude the ditching of wt, like say if you need to
flaot on the surface for a while waiting for the coasties. but even with
a v wt the 80s arent going to be as heavy as empty 104s. JIm i didnt
make this up, i got it all from George, who you folks seem to listen to
very selectively.
im not going to strain thu your last 100 posts about 80s, because
frankly, who gives a fuck. what i would like is some admission on your
part that you dont know enuff about double 80s to make the claim that
104s are better.
