I have used many soft plastic worms ranging from Zoom, Culprit, Berkley (PB) to the generic bargain bin brands.
I was at Wal-Mart the other day and decided to give the Gulp 7" turtleback worm (Cherryseed) a try so I picked up a bag. I went fishing this evening at Yatesville Lake (KY) and was fishing from the bank, casting into laydowns. After a good 15 mins or so of no bites, I finally started getting some nice solid strikes and ended up hauling in 5 keepers! One was a good 24" and probably weighed about 5 lbs. The rest were 15-20". They were simply tearing up these somewhat delicate worms. I ended up using about 8 of them and on the way back home I picked up 3 more bags in Cherryseed, Blue Fleck and Green Pumpkinseed. Berkley has really outdone themselves on this one and found a Powerbait killer. Props to them!
All in all it was a great day and I regret that I didn't have any means of taking any photos but I'm planning on going back early tomorrow morning and I'll have my cell phone with me.
