Berkley Wakebull.
I stopped in to a random tackle shop up north a few years ago and bought one, not even knowing at the time what the hell a wake bait was. Turned out to be an amazing lure for the areas I usually fish, caught some d**n nice smallmouth on it. Stopped at the same shop the year after, they had a single one in stock so I bought it as a backup. Didn't think I had to worry about it being discontinued so I didn't give it too much thought.. when I wanted to grab a few more, out of stock everywhere!
I've picked up a few different wake baits, but that Wakebull has always been a slump buster for me.
