I'm still learning about the different techniques and all so bare with me as I try to relay exactly what I have tried.
I'm fishing various types of worms ranging from Sink-O's from Bass Pro (weedless on a Gomakatsu EWG 4/0 hook with and without weight), KVD Sexy Frog, and a Texas rig worm with the same Gomakatsu EWG 4/0 hook.
I've approached the weeds from my Jon Boat about 10-15 yards away and also tried to fish it from the bank. Each time it seems like it will penetrate the weak spots, but come back to the surface instead of stay under the weeds. (Keep in mind the weak spots are few and far between and not very big). Maybe I could use more weight to "Punch" through? I'm guessing that's what you ment by Punch? lol
Im going to look into the Kreature bait mentioned in the reply above. I bought a pack of what I think is a similar bait from Bass Pro just last week. The name escapes me, but it's a flat rubber speckled frog?? I believe that is close to the Kreature bait you mentioned.
