I use to go through about two or three poles a season. Then I got some of "The Royal Shafts".
They look fucking sweet (Multiple graphics to choose from), they're indestructible. And they have a lifetime, no questions asked, warranty.
I got mine at Christy's Sports, and I can't find a website. But looks like you can get them here:

I know they're pricey, but it's the best pole I've ever had,I would look into em.
