The Rocket Rod pole & addons are initially very expensive, and then drop by a standard amount every hour (like the pole does), until they are only 16-18k. Pole leveling starts at 80 exp. per level before augments. Note: If you haven't yet gotten to or finished Parribea, it is best to wait before buying new poles/addons at full price "to avoid getting stuck" if you don't have the gold for future poles/addons if you decide to race with others.
