I've been happy with my Omniums, but not thrilled with them. I had to file the back of the spiders because the thickness was not uniform(I had a set I returned to Scrod prior that was seriously bad), and I managed to flex the DS crankarm 5-7mm into the chainstay. I wouldn't buy Omniums again, I'd probably go with Dura Ace just to try something new. They're a track standard and there is a reason for it.
