hi Cycco,
You and others here who build wheels are sources whose comments and opinions I always take seriously.
I still feel that lots of people who never get their wheels checked and go eons riding them, and then put a bunch of weight on them, will still benefit from getting at least the spokes tensioned properly--that is the extent of my comment.
Ive always found your explanations interesting, about the rim moving up on impact, and how the strength of the spoke is a big factor. Unfortunately, I just don't have the experience you guys do with building wheels, Im just a regular joe blow who can sort of true a wheel, but just tend to leave doing a really good job to mechanics that do this all the time--knowing that I will probably make things worse if I get into things too much, and thats ok, Im fine with paying once in a while to get things checked out.
In general, in my household, our wheels stand up really well for years and years, but we are all lightweights and we dont have small spoke count wheels anyway.
