The Carolina Fixe range are one of my personal favourite jigheads. I use these with my Xlayers, Spindle Worms and small One Up Shads.
You can achieve a darting action to mimic a dancing baitfish, like a sandeel or sprat, or if you want to twitch the lure like a small blenny etc on the bottom, then the pointed head seems to snag up alot less than a round jighead.
As with many of my jighead rigging I apply a small amount of super glue to fix the softy to the head.
The 11g 4/0 here is ideal for the Original or Giant Xlayer, and the lightness of this lure is great for fishing on the drop or over weed. I now use this jighead and the 13g version a lot when using the Megabass Spindle worm.
