The other day I was fishing a spot right next to a friend, and he was catching fish more than me swimming a senko. Not even the paddle tail ones it was Texas rigged and he swam it in. I threw cranks at all depths and caught a lot less does anyone else find swimming a worm like this can be more effective? I also tried senkos just not swam and flukes and even a Texas rig but again didn't swim it just dragged it like I usually do.

There is an article here I will link you to when I get home since I'm on my phone now. I think its called fishing like an idiot. Its a good article. Maybe someone can pull it for you before I can.

I know Bass Pro has a Swimmin' Senco that is effective. Maybe the fish just liked his presentation better.

I've had great success swimming finesse worms

Swimming a worm can be very effective, I personally like zooms speed worms for this technique, but have had success with a variety of worms.

Rage Tail Anacondas. For the win.

I've never tried swimming a senko but I have swam ribbon tail and curl tail worms with some success before. I pick those because of the action on the tail. I might have to try it with a senko now too.
