Thanks to Scott and Steve for the responses. I'll keep them in mind. (And Scott, the next rubber band Huret I come across is yours.)

Funny, just the other day, a denizen of the iBOB list asked if two heads could be connected to one sensor. I assume he waanted to double the amount of information displayed. That might work with just a SMOS (Simple Matter of Soldering), but I wonder if it would be better to just run two complete setups, one driven off the left side of the wheel, one off the right. For symmetry, you'd probably have to run center pulls or cantilevers and wind both wires down the cable, before separating them to run down both fork blades.
