Last year For Burrington I ran 38/16, and for Bank road 39/19, considering those are pretty much the extremes of hill climb courses I would imagine that a 6 speed setup with a 15, 16, 17, 19, 21, and 23 sprocket would probably work quite well for almost everything, with maybe the odd change of chainring?
you certainly don't need the range from 11-25 on a hillc limb bike anyway, not unless its a course with a downhill in it or something, and then I wouldn't ride it.
False economy though innit. I doubt you'd find a six speed block that weighs less than 167g, and the lightest modern cassettes are normally one or two pieces so sprockets can't be removed.
