You had a pretty good line after your roll, keep moving down river. Don’t always need to catch an eddy. Split second decision that comes with experience. I fuck up on rivers all the time. Glad you’re okay! Isn’t this sport fun?
That's actually a really great idea that I may try to introduce to my local set of paddling buddies next time I see them. First because some situations can limit your line of sight as you mentioned, but it would also be an extremely valuable tool in any sort of rescue/setting safety situation where the roar of the water is too loud to hear anything over. Ive dealt with a few of those high noise situations where simple helmet taps would have solved absolutely every communication problem...
