Why not just use your fulcrums, I've been using mine to commute across London and there fine. The roads are not that much worse than those in sunny surrey. That stretch after box hill is worse than anything I ride over on the way to work. Also unless you tinker with your rear mech, not advisiable unless youve got a phd in bike tinkering changing wheels can sometimes put the indexing a bit out of syn.
If you want you can have my old rigida rear wheel that came with the giant 18 months of riding every day and I didnt even need to get it trued once. its got a 13 - 26 cassette on it.
see you sat
