     I returned from a cavern class at Ginnie 5 weeks ago and they teach 
     you to wrap your line around a rock, not specifying up / down, 
     clockwise / counterclockwise, tighten the lock and leave the spool in 
     the cavern. That complicates things in that you would have no idea 
     which is the loose end of the spool because you leave the line in 
     place to be retreived at a later time.


     Regards,

     Mike

One of the things that I and those that learned to dive wrecks with me, 
learned was not to make things more complex than they have to be.  Thus, 
the direction things are twirled became more complex than simply 
remembering that the end that came loose from the wreck last (when 
untwirling) is the way out.

This comes from the fact that it's easier to twirl the loose end around an 
object than it is to twirl the end that's already attached to (an earlier) 
piece of the wreck.
