I have that combination, 28 2x front and rear (154 lbs) and think it's a great wheelset. One thing to note is that larger riders were getting cracks in those rims so the company thickened the rim maybe a year ago with the 32 hole drilling, adding grams. It is unclear whether they also did that for lower hole wheels, given that smaller riders are perhaps less likely to crack them. I have read VERY few complaints (and lots of compliments), and I have two sets with zero problems after a year using non-reinforced rims.
Great hubs - some very knowledgable people think they're absolutely in the top tier (probably with DA and Record).
