LOL! Sounds like fun!
When a fish charges you, you can turn with your flippers so you are facing the fish. Then reel in like crazy while also flippering like crazy away from the fish.
I've been in the unfortunate situation of having a large trout run circles around my legs. You guessed it -- I was completely hobbled, and lost the fish. Another of those "I hope nobody's filming" moments.
