Create a 'Bastard Child of the Dean' to attract the previous AAA points, if and only if the org can be arsed.
BUT most definitely leave 'The Dean' as it is., AAA points reduction or not. People ride that route because they like it. Not because of a bit of AAA. That route performs a function of a testing early season 300, that can still be ridden in all but thd most horrendous weather.
