One of the greatest lures to use on topwater is the Heddon Zara Spook. The lure is just filled with big catching power. I personally like using the Zara Spook Puppy, it's smaller and a little more efficient to use. All you have to do is take a cast and twitch your rod tip side to side, definitely try to keep your rod tip down near your feet. Once you get the hang of it you'll find that the lure is very easy to use. After twitching the Zara Spook 10 or 15 times, stop for a brief period of time, even wait for a long period of time if you like. This small stop will give the big fish a chance to hit the lure. But, this will not always work, it depends on the conditions. Sometimes the fish are hitting on movement, sometimes they are not. This is definitely one of my favorite lures to use in my tackle box, it could be yours too, once you find out how fun the lure is to use. Another plus side is seeing the fish jump out of the water trying to hit the lure, it's truly an amazing site to see. If I get a video camera this summer, which I want to do, I'll be able to post videos of the fish jumping out of the water trying to hit the lure. There sure are a lot of different colors to choose from as well, I love the flashy silver and black colored Zara Spook, it's pretty much a flashy chrome paint job. There are other colors like the ones I posted below, it's up to you to decide which one works best in your lake. Trial and error is probably the best way to go. I would definitely start of with the silver(chrome) and black color though.

This is the color I like, it's very flashy and gives off the best appeal for bass and pike. Great color to start off with, basically because we all know fish go after a flashy minnow color.

Here's a large assortment of colors, I don't know how current these colors are on the Zara Spook, they might be outdated. This gives you an idea of how many types of colors you get to choose from.
