Your comment might be humorous, if not for the present situation---where an instructor could be so negligent in their ability to get a student set up in their gear ( if student shows up for class in bp/wing) that the instructor could very well FAIL to teach or assist this student in any meaningful way)....And to insist that the instructor should only have to be familiar with jacket type junk gear is ludicrous.... ( this being the way many of us see stab jackets for diving--and the way many students are hearing it from us, that stab jackets are "sloppy gear" they should stay away from....., and thus they are showing up for a class in bp/wing gear) ....
In fact, I get to speak with a large number of people considering dive instruction....and I always tell them that the jacket style bc's are a huge mistake...and not to listen to anyone pushing jacket bc's
Typically I tell them to TRY or DEMO several BC's as well as bp/wings...and to try several types of fins....Diving needs to be more like Snow Skiing where the DEMO precedes the purchase, most of the time.
Like it or not...there is a very real "division" in diving...Insist on things being done the way they were in the last 20 years, and not evolving, and a new agency will come in and take advantage of this growing "division".
Let me start saying that if, in order to understand what you are saying, I need to translate from Lake Worthian to English, perhaps some remedial training about writing skills would be advisable, whatever the agency.
Junk gear might be what you wear, no need for ludicrous name calling, here or anywhere. Calling yourself a divemaster you should show a little more professionalism towards the industry and a far less cavalier attitude about people preferences.
I'm not sure based on what competency you talk to people considering dive instruction, but you should probably get off the pulpit to be taken seriously, the smileys just don't cut it.
