I'm using CRGs as well. No apparent blurring, although they are quite convex. They're perfect for low bars, where the rider is leaning over the gas tank, and the bar-end mirrors are nearly in the line of sight. As a straight-up rider, I found that I had to dip my head to check before changing lanes, and I wound up installing a conventional trapezoidal flat mirror on the left side at eye level to give me a quicker read of the left lane.
