The Nitro has a walk the dog style action with a belly roll.When worked with longer pauses it has a tendency to glide slightly downward.On the next tap it will glide slightly upward.The bait also has a waggle on the glide. The Nitro was made to be an erratic working glidebait.It can be worked slow to fast.The faster you work it, the less waggle, but it still has a belly roll.The bait sinks about ½ of a foot per second.
