Out of interest what are your thoughts on the Park TM1 spoke tension meter? I am thinking of getting one for future builds and maintenance.
It's a valuable tool, precise enough for its job, and easy to use. But for small diameter wheels and hub motors, it's often not possible to find space in the spoke pattern to get a reading. So if either of those things is what you're most likely to be building, then buying the tool might not be worth it.
