Just some recent thoughts...
1. Ski footage from chest cams - about as good as Aids. Looks great for biking but for skiing it's horrible to watch. Resorts should start hotlisting passes for anyone seen wearing a chest cam whilst skiing
2. The new stabilisation feature on the new Hero 7. God that sucks. It's so over the top it makes all footage look super unrealistic and over edited. Also makes the terrain look well too easy/mellow which has always been an issue with GoPro footage anyway
