Go ahead, keep changing your stock units... I will be the only one running with the stock units and my bike will look unique! 
Seem I am the only one that likes the stock units... visibility is frigging great with them. 
Unique is fine
but for me uniqueness ends when ugly over rides unique.
My issue with the round mirrors on the 12 SERG is that they are not part of a matching collection set on the bike.
The mirrors do not match the shifter linkage, the shifter, the hand grips, the floorboards, the breather or the side covers.
I'm not sure what they are suppose to match or tie back to. Maybe I have missed the entire concept of the round mirrors.
Each to their own I guess.
Of course I will keep the stock ones to go back on should the 12 SERG ever leave it's home.
But if that does happen, as it leaves I will take that last look and think, those mirrors are as ugly today as they were the day I brought that bike home.
