Like Indra said, the banking at Manchester is much steeper and noticeably equally steep top to bottom. Ironically, there is probably more risk of pedal strike for a novice rider on a more gradual circuit as the tendency to lean through the curves is much higher. No idea though, what the rules and regulations are at Herne Hill in terms of crank length and bottom bracket hight.
