Here's a great tip right from Pete Maina himself, that I've used countless times.
When the water temps are high, there's more oxygen near the bottom, SO, point your Musky on a 45 degree angle, head down.
You'll almost always get a twitch right away, & she'll be gone very soon afterwards.
Ever notice when you're standing in a lake your feet are always colder than your waist?
And NEVER pull a Musky towards you. This rushes water past the gills alright, but you're drowning the fish.
That might explain why they don't swim backwards....
