What are you thoughts on under spins with swim baits?

How often do you change your line?

I won my club championship last weekend up here in the northeast. I started out with topwater, swim bait and swim jig then moved to 1/2 oz. jig on docks with drop offs and weeds. I caught a bunch. I spent the rest of the day with a jig. These are great fall baits. Should a jig always be in the arsenal?
