I broke another rear spoke on my old Wolber wheel during my commute home a few days ago. I did manage to nurse it on home that night, but I've taken it out of service until I get it fixed. I've probably replaced half the spokes over the past 9-months, but have decided to find something stronger that can deal with the additional weight I've added to the bike. My LBS has a couple of used 40-spoke wheels around that should be much stronger. I'll let you know how it progresses.
