One thing I noticed. I am not using the MFC fin that came with the board as it is big 24cm deep fin so not really appropriate for that board but it would be good when a brand includes the fin with the board, that the fin fits the fin box It looks like it is a US base fin and the board is equipped with some variation of Bahne box. If you ever want to fit the fin in the box, it will take some sanding and possibly moving the pin.
Maybe its just a shipping error, if that fin is offered with several boards in the range. Might be worth asking the retailer to check that the fin fits before accepting it, I guess.
