Catching two bass on the same lure happens once in a great while. With the exception of an A-Rig, you're lucky if it happens two or three times in your life. It's an experience few forget, but the actual fight is forgetful. I love topwater (who doesn't?) and for more years than I care to admit, I've been using a little known, or should I say talked about, way of not only catching two bass on the same cast, but enjoying the fight from each of them. That little gem is called a FrontRunner. It's a little, single treble hook, floating lure not much bigger than a quarter that is exactly what its name implies. Attached to your main offering using a short piece of mono, it will dance in front of it.
The dog days are the best time that I've found when this combo really shines. Sometimes you'll catch them on that little piece of floating balsa, but most times that main offering gets 'em.. For some reason, during the dog days you'll get one on each and because the two lures are separated, the fish fight independent of each other. The fish will, more often than not, be the same size, but on a 'rare' occasion that main bait will get a big girl with a dink on the FrontRunner.
So why settle for two or three doubles in your lifetime when you could get two or three every summer?
