Is anyone else having a lot of sucess with this rig? I don't use the Jackall worms, just a 6" Roboworm Straight Tail on the wacky jighead. I can't keep the bass off of them at the local ponds.

I've been using Gammy wacky jigheads as well as the Zappu heads.  Both work well, the Gammy twitches a little better, but the notch in the head picks up grass.  Speaking of grass, going down to a 3/32 weight head will let the bait rest on top of the weeds.  You can even twitch it right there.  I've use all kinds of plastics for this, including Senkos, Berkley Shaky Worms, Finesse Worms, other hand pours, Trick worms, etc.  Its such a good tech, especially on spawn and immediately post spawn fish that are logy, that I'm not really sure if it really matters what worm you use.  Its yet another lite line technique I've picked up in the past few years that turns tough days into fun days.

have any of u guys fliped with this ??

Flip?  As in use a flip cast?  Sure, you can but generally you cast to spots from a distance.  Its a finesse technique, which doesn't preclude flipping, but I generally use a flip for targets in close.  If your on them, and they don't notice you, go ahead and get the bait to the spot with whatever cast you want to use.  Its what you do after the cast that catches the fish.
