I still get a lot of head movement, but I'm getting a little better, should see the video I trim out.

The mirrors work ok, not my favorite, but we're on bike when I got it.
Hi,
First of all, sorry for my absence since last three weeks, not enough time

Second, it's only a suggestion, consider also the possibility to install the camera on your chest, or on the shoulder.
In my personal opinion, this could be a better compromise between your style of ridding (being careful at traffic, scanning area, the other riders/drivers) and the comfort of the viewers...
Or you can try to mix two footage at the same time, from your phone, like a selfie video and the camera...I've made an experiment in last weekend, see below the link:
Feel free to ask, I will gladly share information, if needed.
From another point of view, I envy you that you have the possibility to ride daily

...for me is not possible
