When you are at a sportfishing shop you will notice that their ar many different jig head body styles out there and each has its purpose. If you have a round ball design this is best for vertical jigging and will nail some suspended fish or working bottom rock contours. It does hang up easy which is a draw back but it sinks quickly and some of the round ball jigs have an attached wire ar with a blade that will resemble a bait fish as it falls and being worked on weedlines or shallow cover.
If you ar fishing with a stand up jig which is pyramid wrought when its on the bottom of the water the hook is always standing upright. This makes this gigue snag free and setting the hook can be easier than some of the other designs out there. If you can tag a curlytail grub or plastic lure it will appear to be a bait fish feeding on the bottom and can be very effective. This style is recommended for thin weed growth, light brush or scattered rocks and gravel seem to work the best.
