Agreed, For me jig fishing is almost all feel. A log will feel different then a branch. Grass is different then rock or mix any of them up however. They all have a certain feel to them. It takes time and patience to learn this. I hold the rod/reel by palming the reel with my finger under the line. This helps me feel what is going on down under the water. Make sure to move your finger before a hook set. OUCH!
The best advice I can give is to go fish a spot of certain structure. Then notice the patterns and how it feels. Once you become familiar with that pattern, move to a different type of structure.
When I'm fishing a jig through brush you can feel the jig up over a branch and then should expect the fall.and feel the next branch. If this does not happen you better set the hook. You will learn the patterns and feel over time. Obviously every brush pile or tree is different but you will learn the feel.
After fishing the brush for awhile move to rock. Feel the jig through the rocks. Learn the feel of the jig.
Then go back to the trees. Notice the difference in the type of hit off the rock to tree. A good rod/line will show you different types of feel from the impacts the jig makes.
Learning this feel with catch you more fish and save you jigs from the Tree bass.
