You'll like the 11-34 cassette, and you can even find a Sun Race 11-36, though it's heavier. I've tried in some hills the 30/30 combo, but I can't sustain the pace for long. The 30/34 is good for tough climbs. And for those extremely hard climbs, I guess it would be better with a triple crankset, e.g. 42/32/22. I've got that combination in a Norco and a Breezer, Ritchey Logic steel, from the 90's.
