I've been switching between a 9.5 Liddle Flex Narrow Base fin and a 8.5 Greenough Power Blade in my 7'4 A.P.E Edge board. Haven't had enough time with the Powerblade to say, but I really like the Liddle fin.
Im not talking about yellowing from a ding. Im talking about a large yellow patch of color that was used to cover up a “happy birthday” engraving on the deck. You can tell from the last photo Ben is purposely hiding the front half of the deck where the patch is.
