fin position on egg 6'2!!help

i’ve shaped a 6’2", 20 1/2, 15, 15 1/2 boards with an egg template.I’d like to put tri fin system( fcs), but compared to a standart shortboards, what would be central and especially side fin position!!!Help!

thanks

Depending on where the WP is, exactly the same as a modern tri…which depends on rider preference, amount of tail rocker, foil of board and rails, and size of fins.

In other words…anywhere!
