Nice brookie, respectable to quick release em. I'm wondering what is best to not lose fish when the current is pulling then away, already happened to me a few times this season.
Think it has to do with increased force from current + trout's inital aggressive head shakes. Might need to let drag down and walk the trout down to calmer water.

This article titled it the kiss off death where it's due to the fish being able to shake it's head while out if the water.
