I use Skitterpops and Rebel Pop R's. Also have mini torpedos and jitterbugs.  A 3" floating Rapala is very versatile as you can retrieve just under the surface then let it float up and sit.  Caught many a fish this way.

I read that BWJ article and Stu has demoted the Skitterpop saying it's a bit hard to "work".  You do have to finesse them that's for sure.  He also mentioned the Z-Pop is discontinued.
