Bites On Senkos, Carolina Rigs, & Other Finesse

[Kawabuggy]

I hear people mention that when you get bit on weightless rigs, that the bite is more of a "spongy" feeling... I have only recently tried Senko fishing and have had some success with them Texas Rigged with the bullet weight.

I have yet to get a bite when rigged weightless. I hear people mention that if the line feels spongy, or heavy, that this might be a fish on. In my limited experience, I have noted a feeling almost like I am hung up. Thinking it might be a fish, I have waited patiently for the line to move, or twitch, which has not happened yet.

Is that all I should be watching for? I have been very patient working the bait while I reel in very slowly and when I feel the bait make contact I immediately stop and watch my line.. But no luck with the line moving or anything else that hint at a fish biting.

Besides the obvious of not getting bit, what am I doing wrong?
