Thanks for the reply.
AOPA has the representation, the authority, the voice, and the channels of communication with the regulatory authorities to do the job. Most of the others (PFA, BMAA, BGA etc) cover a particular segment rather than the whole scene. Therefore I think AOPA has the ability to make us heard. If it's not doing that job properly then we need to sort it out, rather than walk away and let it die.
Philip Whiteman is doing a good job with "General Aviation", in the pages of which it is possible to see quite a lot of what is going on, however its a small organisation with few sources of income.
