I use 720, 1080 takes a whole lot of computer to edit along with space.
Helmet mount is sturdy, just tether it to the strap or a vent. Extendable monopod fits in my backpack when I'm not using it.
Not sure, I have the previous model and don't see a reason to upgrade soon.
How do you reccomend tethering the helmet mount? It can't fit through a vent or fit through the rear strap. I don't trust the adhesive either. Just zip ties to loop through a vent securing the top/side straps?
Wouldn't the video come out blurry with it on your head?
