I've thought about this one too. The QRH says nothing about 'Land at the nearest suitable airport' which may lull you into a false sense of security however, if you bumble along at FL370 in the dead of night and loose the 2nd HYD system....then your calling for the 'Manual reversion' checklist....My attitude may be conservative, but always stack the odds in your favour...Get on the ground, let ops worry about the onward flight, engineers about the tech aircraft and handling agents about the pax...You walk away license in hand.
