3.5"- 4.5" swimbaits have become must have lures for me over the past year. They're extremely versatile and they'll nearly always put some fish in the boat. I've caught everything from big crappie to musky on them. The more time I spend with them the more uses I find for them. Plus they're easy to pour. I also consider sticks,craws,tubes,and worms essential if not as versatile. Thankfully pop is cheap and makes great molds. I too recently started pouring,and I've gone through a pile of it with no end in sight.
