Don't listen to that, the gotcha will definitely catch more blues than a sting silver. A buddy of mine went with me to the Bogue Inlet Pier here in NC last spring and in one hour we caught approximately 40 blues, kept 16 (we split them 8 and 8). All were big enough to keep, as in you could get plenty of meat off them, we just figured we would only keep what we would eat that night with the family. I have never caught more blues or spanish on any other lure than this one. The trebles are no problem to remove, I don't know why someone would think they are. You should be using pliers to remove a hook from a toothy fish anyway, not your bare fingers. If you've ever removed a treble hook from a fish using pliers (i'm guessing you have like every other fisherman) then you will have no problem using this lure to catch fish and removing the hooks from the fish, buy it, it's the best purchase you'll make. All I take when I go to the pier is a plano box, inside that box is a spool of spare 30 flouro or mono leader, about 6 half oz gotchas in assorted colors and about 3 sting silvers. I use the sting silvers for grey trout, the gotchas are for everything else.
Red head/white body and green head/white body have caught the most blues in my experience. The small ones that were mentioned are good too, but better suited for the normal dock and inshore boat than the pier. Cast and jerk back repeatedly, moderately fast for blues, very very fast for spanish. Don't stop till you get bit, there is no pause when fishing these from a pier.
