From what I've been readin, LL has the advantage of covering more water, flats, ledges, channels, etc. I figure spider riggin has the advantage in fishin cover like brush piles, stake beds, trees, etc. I'm just learning to LL, but that's my take on it. I think spider riggin is way easier. Don't have as much depth, jig size, line out, and speed to figure. Gotta take a lot of time on the water to figure LLin out.
