I'm after a bigger fin for my Fox 140, I'm thinking something in the 48-52cm range and more of a powerful race fin than a Freeride fin for those light wind days with the 8.6. I can find and have some nice Tuttle box ones but nothing in power box.
Any ideas? If I can get them in Canada even better.

last resort is taking a file to one of my tuttles and converting it, should work as far as width is concerned but the powerbox is slightly longer so there would be a gap at the front and back, not sure that would matter to much?
