At what spoke tension?

At 110 kgf I got over a decade out of my last Mavic Reflex clincher (a lighter open pro) front.

That's just short of the elastic limit where I arrived using the Jobst Brand method of tensioning to the elastic limit and backing off half a turn.

With any more tension one should expect fatigue failures at fewer miles.

And they build up into weak wheels because of the low profile. My poor powertap hub's been build up five times now- the Open Pro builds lasted less than a year.
At what weight, tire size, and pressure? I didn't bend that Reflex until I'd grown from 145 to 205 pounds, was still riding 23mm tires, and wasn't adding air every other day.
