haha you can't recommend poles for someone over the internet. some people have much longer legs than torso. this creates the need for a longer pole... the only way he can determine what size pole he needs is to go to a shop.
im like 5 8 or 5 9 and i use 42 but i wanna get like 40. i like short poles cause your not dragging them when you dont want to use them and i like it better for park stuff.
