What size fins are you using for sails over 8 meters? Does it depend much on the board size?

I have been using the biggest 42 with up to 9.5 on my Isonic 121. Yes it does depend on the board. If you were to be using a formula board then you could go 70 cm.. Just to reference it.

Thanks for the rapid reply. I have no experience with Formula boards and was wondering about the 70 cm fins I have seen on them.
