Hello! I can't believe I nearly missed this!!
I'm not an expert on board design, but if you're a goofy footer it seems like most of the boards you showed have two fins and more of a pin tail (to be more stable almost like a semi-gun) when you're on your backhand and then only one fin and a wider tail (to be faster and looser almost like a fish) on your forehand... is that correct, and is that how it lands up feeling in the water?
Yoooo. It's really amazing that this operation of one side of the board is like twinfins at last and the other side of the board is like a gang.. quadri fins... this aligned with all the design of Dec beak and tail makes you feel very good in the water to the innovative feeling and the real one bro! I recommend to you my friend but doubts send a hello and we talk more! Aloha
