It can be confusing for sure. I think time and experience
on the water will hone your instincts for what is a bite
and what is not.
This is why TV shows make it sound easy, these guys like
Hank Parker, Jimmy Houston, et al., have YEARS of
experience and can tell a blade of grass from brushing the
fin of a shad on your way though a grassy flat. (I kid, but
it's almost true ).
I remember when I first really concentrated on jig fishing.
I was looking for the mushy feeling Hank Parker talked
about. Nope. Never felt it. But I kept at it, and even when
dragging through a weedy area, I'm now able to tell when
I get a hit, mushy or not. It is purely instinctive now, taught
by experience of throwing over and over and over.
Sometimes when I catch one I try to wade back in my thoughts
past the adrenaline and figure out what I felt and how I knew
to set the hook....
As for worming like Wacky and Texas (which is somewhat
similar to jig), I do like using yellow braid for those bites that
are not detectable.
Don't know if this is helpful at all. But some awesome responses
from the others above, like @Catt. Learn from these guys.
