I think Joseph B-Z is confusing the Weinmann Concave rims with the less expensive Weinmann rims that resemble the current Velocity Twin Hollow parts.
In any event, I had the true Weinmann Concave rims on my tandem on my tandem and they definitely had eyelets. Also, they struck me as both stiffer and having a harder surface than the Super Champion 58s.
My wife an I put thousands of miles on those rims, loading up the bike with both front and rear panniers. We also put thousands of miles of Super Champion 58s, when we switched from 27" to 700c. In my experience, the Weinmann was the more reliable rim.
The is no denying, though, that some spoke wrenches simply will not work with the Concave profile. I will also concede that the Model 58s were easier to clean. Whether the Model 58s were actually more aerodynamic - in practice on a built up bicycle - is debatable.
Parenthetically, this is what I mean by loaded:
