For my own peak bagging purposes, I have now turned my back on the Munro Tables and look to Alan Dawson's "Relative Hills of Britain" - the "Marilyns" - summits with 150m of clear ascent all round. In Scotland, I now bag "Marilyns" whose summits are 3000 plus feet above sea-level.
Yes, from now on I'm only going up Marilyn Munros!
But, all joking aside, a record attempt that only covered hills of Marilyn Munro status would possess a truly definitive criteria that could not be tampered with, and could stand apart from the current Munro record.
