Here in the SB site, in the FE page, is write that the delivery fin is the Drake R19 70cm!!
If is the same board of last year, can I upgrade my Drake R13 with the Drake R19??
The F160 tufskin is deliver since last year with a Drake R13, so you can use only in Formula Experience the fin who is deliver with the board.
But yes this Drake R19 increase the performances.
All the best
