imo most of the time you want a feeling of speed with a chest/bike mount, so you’re probably not going to use the half-speed option of shooting at 60fps very often. if you’re also using it on a pole or whatever for off-bike shooting of other people however, that’s when it comes into its own.
having said that, if you shoot at 1080p, that’s a narrower angle, i.e. more “zoomed”, so you’ll get less of the bike/your arms in. 720p is wider. 960p is the same wide angle but at 4:3 rather than 16:9, and so probably less desirable aesthetically for most people. also won’t mix well with 16:9 footage shot on a dslr or whatever.
the other consideration is that 720p is a lot less painful to edit with, if your computer is slightly older. it’s also less detailed but depends what you want to do with it, and tbh while a gopro is great quality for what it is, it probably doesn’t benefit hugely from the extra detail of 1080p when bombing through a dark forest.
I almost always use mine at 720p, 60fps.
