I've thrown them a lot for nada, but the few times I've scored makes it worth it, and I haven't even come close to hitting the jackpot- watching guys like Cam throw them ALL day showed me that it takes a lot of effort but if you put in the time it pays off, it might be that last half hour when the wolfpack shows up and makes a slow day one to remember. We're lucky to have some guys on this board that have really got it wired, keep your eyes and ears open and you can learn a lot. It's definetly worth the effort involved.
Here's a medium one from Dixon on a day I figured they wouldn't want the swimbait- sheet glass, super clear, and 10 knuckleheads crowding the bank around the channel she came from- go figure!
