Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

For what it's worth, my current training wheels are a set of 32H DT Swiss 585s laced to Shimano Ultegra hubs with DT DB 2.0/1.8 spokes and tensioned to 135kgf on the drive side rear. They've been absolutely flawless under my 116kgs for over 14,000km. Two tension checks in just under a year and a half and at both of those, no truing was necessary and only the most minor of tension equalizations to be performed. I do a reasonable amount of urban group riding and subsequently hit plenty of stuff at moderate to high'ish speeds.

When I moved here in 2008 I was on a pair of Open Pros that quickly suffered from the local abuse compared to the more moderate and smooth riding I had been doing for the previous 6 years. Over the next 2-3 years I went through a number of other rears before settling on the 585s. They're not light (2000grams), but, they are as close to bomb proof as a road racing wheel can get.

They're easier to cross and easier to build with even tension. Plus he said his budget is big, so why not?

This wasn't a one off bad batch. The issue went on for a few years and guys who had been ardent Open Pro devotees eventually had to give up on them.

The rim manufacturing world moved on, while Mavic and their Open Pros did not.

At this point, if you want a sorta' retro rim from the 90s for a period correct build they're still available. But, barring that, there are now better choices that are either, lighter, more aero, more durable or less expensive.
Hmm, that doesn't seem like anything new to me. I've still got a couple of Mavic rims from the '90s/early '00s, a pair of 517s and a set of OPs that both have small cracks at the eyelets. I thought that was pretty normal for hard-worked, lightweight rims. I still ride those cracked 517s, in fact, because they are that cool lime green ano color that just look boss with the green frame!

I think Sapim would say that they're stronger and build a more rigid and durable wheel than, say, a round Laser spoke, too.
