Exactly Alan. No amount of rule changing will bring Brian back nor decrease the chance of similar fate befalling any of us who chose to deliberately put ourselves in harms way by doing a fell race. By following your suggested logic of high personal responsibility contributing to safety you could argue that the rules should have been SIMPLIFIED not increased or made more comprehensive. I think what Always Injured is repeatedly pointing out is that the more you say, the worse it gets. Say less and keep responsibility where it should be....with the individual.
Of course, this is all very well if your organising committee is just a group of like minded individuals. Damn near impossible if they have transformed themselves into a limited company (as pointed out by our Welsh Chair). But thats another kettle of carp altogether!
