Herr Jobst Brandt claims that tension spoke wheels should have the spokes tightened to the limit of the rim's ability to stay true [1] while statically unloaded to maximize lateral strength of the wheel. However, Herr Brandt's sock puppet detractor, "jim beam", insists this will lead to premature fatigue cracking of the rim.

However, spoke breakage is caused by fatigue in the spokes- the looser the spokes, the more they move, and the quicker they'll break. After the wheels are trued and tensioned, you may break some spokes. If this starts happening, you'll need to have all the spokes replaced. There's no way to stop them from breaking once the fatigue process has started. Jeff, If I recall correctly, Jobst Brandt reported cases (in the 1960's, I think) of his wheels breaking spokes. Said wheels had the broken spokes replaced, were re-tensioned, trued and stress relieved. Mr. Brandt reported that further spoke breakage did not occur on the subject wheels.
