	Just a little suggestion, since I for one am getting well
confused here. Why don't we differentiaite between lifting bags (used
for bringing a massive load to the surface from depth whether by careful
buoyancy control, fire-and-forget or reel deployment) and delayed
release surface marker buoys (DRSMBs, used for deco hangs and as an
ascent datum, whether shot off a reel or deployed on short lengths of
dedicated line).

	Following Reg's comment on not dragging 50 feet of line beneath
you, yes it is a problem but how often are you going to be hanging for
long enough to need a DRSMB when the water is so shallow?

	Cheers

	Jason
