My observation is that everyone on the board, for the most part, agrees that DIR divers have great skill sets, ie trim, bouancy, finning techniques, etc. Most seem to agree that they get these skills from GUE Fundamentals, and that this is a great, almost vital if seems, class to the becoming a better diver. My question is that if this is the case, and the class is so important why put the gear restrictions on divers who want to take the class. In all fairness what is the major difference in configuration of a bp/w and my Transpac if I have no intention of going DIR, and but simply desire to obtain better skills.
