Quad Lock handlebar vs clutch perch and bar-end mirrors

[Uncle Sixer]

So one of the reasons I love the CB so much is simplicity and I hate to put on a phone mount and mess that up, but it would be good to have my phone mounted as a navigator sometimes when I am off exploring unfamiliar back roads that are not always well-marked.  I am looking at the Quad Lock system and trying to choose the mount.

I see they have a mount for the brake/clutch lever perch.  I like that it would not be more "clutter", like another thing clamped onto the handlebar.

But, the handlebar mount might be more versatile for different mounting angles and locations along the handlebar.  And, maybe a little easier to remove if I want to go back to a clean look.

I am pretty sure I do not want the phone dead-center.  I am also pretty sure that for either mount the vibration damper is a good idea, right?

I guess also on a similar note, any recommendations for nice bar-end mirrors that give a good view and look good.  It would be good to keep some weight out there, right?  I think round mirrors just under the bar ends would look great on my bike...

Any thoughts?  Foreign territory for me, so I am in brainstorming mode
