You start out with the Teacher's Pole, and I see that one of the rewards offered by the Fisherman who teaches you to fish is the Old Man's Pole. What's the difference between the poles offered in the game? Does the cursor for catching them move slower? Is the Impact area larger or does it do more damage? Do I get more chances to successfully catch the fish?
Basically, what advantages does the Old Man's Pole have over the Teacher's Pole (or any other, if there are hidden ones)?
