If I’m going somewhere new I like to watch POV full runs (even did before the Mega) I understand the trail get flattened but it gives you an idea.
Generally though external are better, however you then only see the “best bits” of somewhere, at least a full run down something is honest.
I also do plenty myself, but they are as much from me/my friends. I’d like to do non POV but that really spoils the riding. With POV at least you just do your ride as normal rather than keep stopping, setting up a shot on a corner, session it, pack up move down the trail and repeat. You get bugger all riding done if your trying to get footage that way.
My vids are here if anyone wants a look and I dont really care if you do or don’t :p
