I'm nothing to do with GoPro but this is what is so good about the new GP5. First up it has 3 settings Super View , Wide & Linear.The Linear will give you the none Gopro look . It has in built stabilization with superior low light and because it's not in a case you get no wind ripping sound from the 3 mics , the sound is amazing , if it's mounted on the boom it will hear you talk to it . Forget the wifi it has voice commands , Go Pro Start recording , Go pro Stop , Go pro take photo. How good is that., and no fogging in hot or cold climates. It also has a telemetry App for to add GPS data which comes up on your videos
Don't worry about the 4k sucking up card space just set it at Pal 1080 x 50fps and you will get dream vision and will slow down silky smooth in post. You spend so much on your gear it's ridiculous to skimp on the camera gear to film you ripping.
Here is a site where you can get 44 GoPro mounts for 32 bucks
