One of the things I like about my CRG Hindsights, aside from the fact I can fold them in for tight spots, is that I have them adjusted to give me a very wide view, covering my blind spots (I still do head checks), but I keep the left one (since I travel mostly in the #1 left lane on the freeway) turned in a bit to show more directly behind me. It keeps its partial position fairly well and I can quickly flip it to full open if I'm in the middle or right lanes. I've never had Rizoma mirrors, but they sure are purty.
