Plants VS. Zombies 2

I started playing P.V.Z 2 maybe a week ago. I am on the Wild Wild West and those poncho zombies are extremely annoying. The split pea is extremely useful for those zombies that fly behind them because they have a repeater in the back and a peashooter in the front. Snapdragons are also good because if you have one column of them with walnuts in front of them, they are really good and do immense damage. The spikerock is good, too.
