What is the Flick Shake rig, It is relatively new to me. I was just wondering What is it?

You might do a search. Someone had a post not too long ago on this technique. Had never heard of it myself...

It's fishing a worm wacky-rigged style on a jig head.  Jackall makes a "Flick Shake" worm and a "Flick Shake" jig head.   But you don't need to get specific Flick Shake heads or worms.  You can do it with  Zoom Finesse or Trick Worm, or Senko, on a jig head like an Owner Ultra Head.

Senko's arent an easy substitute... I'm big on wacky rigging senkos, but when the fish are killing flick shakes, i've tried throwing senkos in the same color, and the results were not there at all. Havn't tried the zoom finesse as a substitute, but brent's slim sticks didnt work for me either.

You can try a Berkley Shaky Worm, too.  

I prefer a jighead that has a straight or almost straight tie point.  I have had great success with Gammy Wacky Jigs, but the little cut out for the line tie sometimes catches weeds.  The Zappu jigs work great, but are pricey.  I've also used Bagley shaky heads for this, and they work well, but have that little baitholder cone on the shank.  Basically, any jig with a gap wide enough to accommodate the worm will work.

Speaking of worms: Berkley Hand Pour, Finesse, and Chaky, Zoom Finesse and Trick worms, Roboworm Straight Tail, and basically anything that fits works.

Cast, let it sink to depth, and gently shake the tip.  Depth, current and lure buoyancy will determine weight of the jig.  I generally use 1/8 oz., but occasionally use 1/4 for deeper.  A really light head will allow you to let the bait rest on thick, submerged vegetation and then shake away.  Its much more interactive than wacky rigged Senkos.

There is very good article in a recent In~Fisherman that details everything about this.
