I think a lot of the problem is the diehards that treat DIR as a CULT-RELIGION,not as a way of doing something.We probely have all sat on a boat and got scolded for our AL80 and AL19 pony(Reg on necklace BTW) by the guy wearing most of the dive shop just to do a shallow reef dive.DIR has a lot of good ideas I use when needed but are overkill at other times. Why can't we all just get along?
