i think you may be better asking some of the
ribble valley
crc, or other preston area, women about gearing, most will have done the climbs and areas that you're thinking of riding in .
look on a club as a knowledge base both for bikes and looking after them. lots of free advice and probably help based on experience of the area.
personally when i'm not on fixed i have a triple with 30x26 bottom gear and have used it many times on the longer climbs, including the couple mentioned earlier, round here when it's been windy or i've just wanted an easier climb..
