I did read about the Ping thing somewhere - isn't that to do with twisted spokes?
Every wheel I've ever built or trued with crossed spokes has pinged.
I generally find a newly built wheel will ping a lot then need trued then ping a little and might need a little tweak and so on until no more ping/no more going out of true.
FWIW, built loads of wheels for myself, lots for customers, mates etc and never used a spoke tension gauge and never had complaints of them going out of true sooner than they should.
I don't really understand how you are not able to judge tightness/tension without the meter, do you use a torque wrench to fasten every bolt on your bike?
