The Hero4 Silver is actually still what we officially recommend (only because we have not been able to test the HERO5 in the heat of the summer....since it came out in the cool of the fall). No issues with this camera (4 Silver) other than stability when using WiFi. I recommend turning WiFi off. Other than that, great camera and has 3 different FOV's to choose from.
Thanks for the feedback everyone! Saved me from making a mistake. Found a good deal on a lightly used Hero 4 Silver that comes with an extra battery.
The extra battery is handy, but I would look for a USB battery to power the camera externally. The GoPro batteries are only good for about 1.5 hours brand new (and on a good day). Most likely, you will find that they are only good for around an hour or less. The external battery will allow you to record multiple games on a single charge and not have to worry about it.
I'm posting this link not to push my stuff, but rather show you what we recommend. Ignore the bracket if you already have plans on a mount. But I highly recommend the external battery and the battery eliminator cable as it is the best way to power a Hero4 with external power:
