A lot of guys from Australia that i chat with use Vector fins, check http://www.seabreeze.com.au/
The Vector Volt is similar to the Talon in a way.
Your best choice is to contact Jeff at Vector fin, and let him know what you are looking for he will give you a good advise, you won't go wrong there.
I am very happy with what he recommended for me.
I just put new order with him 42 Canefire and a 40 Volt wide.
