Let me get this straight--
you do not like PADI because many PADI instructors still teach students on their knees, despite PADI pushing otherwise. Please list all the other agencies which have all instructors teaching students off their knees. It will be helpful.
You do not like the fact that some PADI shops require instructors to wear specific gear. Is this a PADI policy? Can you name agencies that do not allow their affiliated shops to do this?
You don't like the fact that some PADI shops are afraid to change and teach with a BP/W (a configuration industry statistics indicate account for 1% of all BCD sales) and have students with lousy buoyancy control. As it turns out, the only shops I personally know that teaches students in BP/W are PADI affiliated. Which agency do you know that has affiliated shops that require BP/W instruction?
In summary--please name the shops affiliated with agencies that do otherwise. (BTW, I used to use a shop that advertised as a GUE instructor development center, and although they did sell Halcyon BP/Ws, the vast bulk of their sales was jacket BCDs, and if you took an OW class from them, that's how you would be taught.)
#1 Look at Instagram, my man. Lots of knees. PADI might be "pushing" otherwise but old habits die hard.
#2 Like I said in my original comment, "I have a few gripes, not aimed explicitly at PADI. Still, more at old school PADI shops who are unwilling to be innovative and focus on quantity over quality" However, I believe SSI has an "official uniform" which requires a certain BCD loadout that they sell in-store. With that said, many LDS I have worked at in the past pushed heavily to wear their gear. It's business, I get it.
#3 Can you please cite your stat on BCD sales? Also, those are the shops you personally know (which I don't know) Nevertheless here are a few examples of ones that I know teach in a BP/W setup, Deepstop, Dive Center Bondi, Eight Diving, EE, Living Oceans, Plongee, Portofino Divers, Scuba Academie, Tech Korea, Zero Gravity et. al.
Cheers.
