Given the dispersement of Service personnel in the MOD, a roadshow plan would be open to all kinds of problems. Some folk will not get a roadshow due to their location, etc, and if in the fullness of time they realise that they made mistake in their choice they could argue that they were unfairly informed, because other people got a roadshow and they didn't.
This is down to individuals looking after their own interests. There is a lot of clearly written info, about both schemes available. Flt Cdrs with junior ranks could convene meetings in their workplaces, with admin staff present to broadcast and explain some of the terminology involved, and generally make themselves and the admin staff available to clarify any confusion.
The current redundancy scheme is muddying the water somewhat, but it too comes with pension info and an option for the individuals involved to revert to AFPS75 if required.
