I've seen quite a few posts that say Open Pros aren't as good as they were in the "old days".

from the posts:
new open pros have serious issues. The newer rims will crack at the eyelets. This is a known issue, my local shop does not use them anymore because so many of them came back.
I have seen a number of Open Pro's (double eyelets) with spokes pulling through and these were not built under overly high tensions.
I've built a few MA3s. They seem rather soft, and I try to stay down around 100kgf driveside, where they seem more stable. Drive them too high and you're likely to have them constantly going out of true... install your tire and tube, hammer your wheel up a few hills, and how true is it now? And for the record, I see cracked Open Pros come through every month or two, the double eyelets ultimately don't work miracles.
