>> so snagging is not really a problem. Make sure there are no rough or

>> importantly your suit :).
>>
>> And finally the ancillary kit.
>>
>> Lift bags (up to four) and goodie bags (1) sit on the back gas cylinders.
>>  They are folded into long tubes slightly longer than the gap between the
>> bands.  Strops and clips are pre-connected but wrapped up inside so they

>> used to retain the Barry Miller backup lights to the harness.  These are
>> cut thinner (e.g. 10 mm) so that they can be easily removed underwater.
>> On each back gas cylinder I have two truck inner tube strips about 1"
>> wide.  The top sits under but near the top cylinder band, the lower under
>> or over (but near) the lower band.  Pre-packed lift bags sit under these
>> truck inner tubes.  The method of deployment is to pull the lower part of
>> the pre-packed lift bag outwards from under the lower tube and then pull
>> down to get it out of the top tube.  This is real easy.
>>
