Thanks, wvridgerider, sounds like we're of similar build and history.
I made my first attempt at tensioning and truing the (about to be replaced) wheel yesterday after replacing a couple spokes. Had no idea what I was doing, and have yet to test it beyond a quick parking lot loop. Before tensioning and truing, the drive-side spokes that seemed "good" were at 25 on the gauge (for 2mm round steel spokes, that should be 120kg per the the table that came with the knock-off Park gauge), and the "good" spokes on the disc side were around 20, so I tensioned all spokes to match that, more or less: 24-26 on the drive side, about 21-22 on the disc side. I have zero concept of how good/bad that is.
Feel free to start placing bets on if, how many, which side, and how quickly spokes break when I go for a casual ride tonight...
