Love it! This fin fit my IROCKER board perfectly.
It also improved the tracking substantially.

I was glad to see you had one in stock. I'm guessing I didn't lock my fin in correctly and lost the center fin. I have not used the new one yet, but it does look like the correct fin. The fin came quickly and the boards we purchased years ago are working great. Thanks.
