Subject: Re what works was Re: Bondage wings (was Re: Scooters)
Kevin, I appologize for this blasphemy - I was agreeing with you. I just
assume that anyone who does not start out a bondage wing discusion with
the words "a friend of mine.." sees this the same way I do. I should
have been clearer in the comment, as I can undestand the severity of the
potential insult. Only a complete stroke would think that a convoluted
pice of nonsense like this could have any possible use. They are
dangerous, they increase drag from current or scootering, they are a
convoltued cluster waiting for a place to happen. Eveything on them is
in the wrong position, and the double bladder thing is absolutely the
single dumbest thing I have seen outside of just straght deep air
diving. 

This is a typical case of gear designed by a know-it-all who does no
diving in the first place, like 99% of the scuba gear out there. There
are so few cases of gear properly done in the first place that I could
list most of them right of the top of my head right here:

TUSA mask
Beuchat Jet Fin ( now the Scuba Pro)
Original Scuba Pro bc ( twenty years old )
Luxfer 80 aluminum tank
pressed steel 104 tank
scuba pro manifold
Dive Rite wing
Flanigan back plate
Martz light ( English, AUL, Gavin, and now Miller)
Farallon fin straps ( now oceanic)
Bill Main spool
Gavin scooter
Oceanic backup light ( now Miller)
DUI TLS 350 ( self-donning, telespcoping, trilaminate) drysuit
G250 regulator and Apeks copy
certain fist stages, like the various states of the USD conshelf,
the varioius versions and copies of the MK20, the Odin, etc
Uwatec bottom timers
Suunto compasses
wetnotes
RMV rebreathers

 These are examples of things that have worked well forever that wre
desgigned by divers who actualy did the diving, and which worked then
and now. Thee are not gimmicks, they are the real thing.
