The mats are creeping up around Central Illinois, and learning to punch is my technique for the summer. So anyone got good videos or articles where they learned something very useful? I've watched a few general videos on YouTube thus far. But I'm looking for the good meaningful tips lol.

IIRC, Scott Martin has a couple very good vids....one just on rigging and a couple on punching...I learned as much from his as anyone else's

Best tip for punching is find a smaller bait without a lot of appendages, which should reduce the total weight you have to use.  Tons of video's out there denny brower might be worth watching.
