Hiflyer,
As I have said before, I think the whole PC3 thing is great.
However, as you know, you do not need anything like 40 % membership to approach BA.
You will NEVER be recognised for "not being bassa". You know that. The other TUs, and even the PC3 supporting branches of BA would be forced to turn against you.
You need a positive statement, and a brand, and brand values, that say what you are and what you stand for.
er, and you must - legally - be financially independent.
By what you say, you have some work to do......
Great luck!
