I got 'em, I love 'em, go get 'em!
Seriously, they work very well and very versatile in their positioning.
If you are going to drop the money for CRGs, then I'd go with the lane split. Even if you don't use for their intent of Lane Splitting. It is a very handy feature for tight parking, you can fold them in fast without screwing up their adjustment.
Keeps them from getting tore up or snagged on something. And I have found make a nice Pseudo hook..
Also, CRG has a good parts replacement policy, so if the glass breaks, etc, you don't have to buy a whole mirror assembly.
Words of caution. If you have stock bars, you'll need the adapters. Tomaselli (3 way adj) bars have enough extra length at the end, no adapters needed. (they thought ahead).
No idea if Helibars allow any extra pipe.
P.S. I have had Napoleons on my bike before the CRGs. The CRGs I found vibrate MUCH less.
Good luck in your decision.
