I have never used them on a shakey head, but over the years I have noticed that the Creme scoundrels will float if they don't have too much weight on them.

SK Elaztec to float. Zoom finesse produce more for me, float or not.

You want a "stand up" head, not a shaky head.  Just look at the description: shaky head, not stand up plastic.  It's an evolution of the jigworm, adding a bait holder and longer, stout hook.  A shaky head is a floating worm, where the jighead rests on the bottom, and the floating worm's tail rises.  Shake the head (get it?) and the tail flops down, and rises again.

 

Now a good standup head (try these, they stand up just about every time: http://www.megastrike.com/#!products/vstc2=shake2-heads) will accomplish what you want to do, and more.  They have a rocker head that offers more control than the standard shaky head.

I use a 1/8 oz SH 99% of the time with either a robo, zoom or swag plastics. I'd go with a smaller wire hook if you want it to stand up a little more.
