I prefer the Premier Series jigs with Alien and Football heads, mainly in 3/8, 1/2, and 3/4 oz weights. Like Hooligan said, the Alien heads are very versatile for fishing around a mix of weeds, wood, rocks, and docks. The Alien Premiers are the best jigs that I've tried.
Black/Blue and PB&J have been my most productive colors this year. Alimony, Junebug, Okeechobee Flame, and Green Pumpkin/Purple have also been very effective at times.
I see nobody has mentioned the Pro Series yet. Don't let the price fool you, these are great jigs and the best value around.
