Picking up on RobF's reply, and Gilly's posts, it raises the question as to how any change to the system might be proposed. It's all very well to say put together a team and come up with a scheme with enough meat on the bones to pick over, but it would need a region's endorsement to become a proposal on the table.
Now it might be the case that my own region decides that the idea is a non-starter. However other regions might just say, that idea has merit, let's talk about it. Those other regions might together form a majority in favour of change, but they don't get to hear about it as it's got no further than my home region.
The other way would be for the BFTA management to commission a study, but that needs to come from HQ, top down not bottom up.
