A couple of weeks back, Hank Parker aired the show where he went night fishing with some guy in California.  The guy showed a modified crankbait for a second, and then hid it from the camera.  I think he added a second treble hook to the split ring on the back of the crankbait.  I might have missed it or seen it wrong, he only showed it for a second.

Would this work, do you think, or would it mess up the action too much?  

Sorry Mods, I meant to put this in the Fishing Tackle forum.  

LOL @ "some guy"

Adding a second treble hook to the same split ring is bound to cause them to tangle and throw off the action of the bait.

Plus, three hooks is enough dontcha think?

I saw that same show.  The "some guy" was only 19 years old and on his way to pro status.  He'd fished that lake since he was a kid and knew it well.  It worked for him so it could work for you.  Yeah, it will throw the action a bit but you would really have to have some short strikers to require a second treble on the back.

I'll admit that I was thinking "hmmmm....that's an idea" when I saw it too.  I don't fish cranks enough yet to actually experiment with it.  Try it with a really heavy action crank bait and see what happens.  Just be prepare to snag it on structure or whatever that much faster.
