I looked at all 3 for my bike last year. I like the shape of the Pazzo and CRG better to the ASV. The adjuster wheel on the ASV is nice but as for being more adjustable; how much adjustability do you need? I found it to be unnecessary for the added price. That left the Pazzo and CRG. I liked the Pazzo for the fact that they're Canadian but the unfinished look of the levers (which some people love) didn't do it for me. Already having CRG bar end mirrors on the bike, I knew the quality was top notch. CRG it was.
As for knock offs, MY OPINION is that for something that your life depends on to not break or crack, no thanks.
