I went 650b after several years of ^this type of annual tyre/guard fiddling.
On my steel road frame the conversion was pretty straight-forward. It gave me the 32mm tyres + full guards that I really rate for winter/night riding. My winter bike has reached a state of low-tech nirvana. It also looks particularly heinous now it sports a crabon™ SMP and huge lights.
Things to bear in mind if you go for it...
tyre choice isn't huge. I think there are plenty of good tyres but you can't walk into a LBS and pick some up, so buy a bunch (and make sure they're folders if you want to tour).
pedal strike can be an issue, so don't use wide pedals.
I think maybe braking isn't quite as tight as on the Campag short-drop Centaur brakes I had before, I'm not sure this is related to the new rims or the nature of (very) long drop calipers. The difference is really tiny.
