I see Craig Cook mentioned... Not in the same class as the majority of other riders mentioned! He is very good, but when you think riders like Wilson, stoney, Watson, schott, Carr, shields all rode in the league at the same time, I think it demonstrates how much stronger it was in the late 90's than it is now and how much tougher it was to stand out.
I confess to being a Sheffield supporter and so am slightly biased, but Wilson and Stoney stand out to me for being 10 point riders with longevity over a number of seasons.
