My Parallex fin is a G10. Heavy stiff fin, but really nice. I used it in the 9’3” Parallax I had. It worked really well. I haven’t ridden it in anything else yet.
The involvement fin I have is Volan and is just a great all around fin that I’ve ridden in quite a few boards. It’s a fuller fin then the Parallax and I like the added surface area.
I also have a 10.5” Classic Pivot fin that is new and I haven’t ridden it yet. A little more area then I like and would be a great noserider fin. Probably sell it as noseriding isn’t really my thing.
