Many anglers place their sense of feel in their rods & line but I think it all depends on whose hands the rod is in period.
My wife could not tell a bite any better with a Berkeley Cherrywood than she could with a GLX but the reason is not rod sensitivity. What was transmitted up the line & then down the rod to the hands was lost by the brain.
Now in my hands if that bass farts anywhere around my bait I'll know it
The art of feeling a worm/jig bite is a fine combination of watching your line and feeling for unnatural sensations of what your lure shouldn’t feel like. Sometimes you will feel that classic “Tap”, sometimes you’ll only see line movement, sometimes your line will simply go slack, but sometimes there will only be a feeling of heaviness that is almost like your lure will not move. The bites where the bass moves after inhaling your lure are the easy ones to feel because there is line movement, the bites where the bass simply inhales your lure and just sits there are the hardest to feel. Feeling a worm/jig bite requires keeping a certain amount of tension on your line while at the same time keeping a certain amount of slackness in your line. To the average angler this makes no sense at all but the worm/jig angler it makes total sense.
Maintain contact with your lure at all times, allow the lure to free-fall unrestricted, but without letting slack form in the line; follow your lures down with your rod tip.
Pay close attention to the depth you're fishing, any sudden change in the amount of line you're using could mean you’ve been bit. For instance, if you're fishing 6 feet of water and the lure suddenly stops at the 3 depth, it's possible a bass has taken the lure. If you're fishing 3 feet of water and 6 feet of line sinks chances are good a bass is traveling with the lure. This is extremely true on the initial drop and no line movement maybe noticed.
