Isonic 107 and NP Rs racing

[emil]

Just ordered the isonic 107. Planning to use the board with 7.0 and 7.8 sail NP RS Racing.
I'm 76kg experienced surfer but not a pro. Usual sea condition quite choppy.
Planning to order to SL4 deboichet.
Can you recommend the best fins in my case?
Thanks

Hi Emil

The Sl4 40 for 7.8 & Sl4 38 for 7.0.

Have fun

All the bet
