Not exactly new to these but this seems to be the only forum I have access.

I'm curious, those of you running gopros externally.  It seems they updated the rules to require a mounting cable in addition to the suction mount.  How many of you actually plan to do this?

2nd question.  Those of you running an app in conjunction with the gopro like TrackAddict.  What do you use to mount your phone?  I've got a Note 5 which is an obscenely large phone but the GPS pickup is phenominal and the screen is a lot easier to read.  But the mount I have right now is barely stable at 80 on the highway let alone hitting 130 on a straight-away.  Thoughts?
