Need Help Deciding Fin Shape

Basic 3FNC but having trouble deciding the fin shape.
Started with the top ones but changed to the bottom ones and am leaning towards them now.
But still like the top ones too.

I like the bottom ones.
Though, if you do go with the top set, I'd make 'em symmetrical trapezoids.

I like the top one, but you should pick whichever one looks cooler to you.

I like the bottom fins. Looks like my Sudden Rush...

What are you trying to achieve? Looks? Performance? Wow factor?

Paper, plywood and wood glue, right?

Pete-
Just for you, yes.
Can that finger planer of yours chamfer 37 layers of tagboard wood glued together?

Johnie-
Looks of course; form over function.
Actually, they both sim quite well, so...

The top on I came up with in RockSim.
I was piddling in AutoCAD to check layout on fin stock and thought I was doing the same fin shape as in RockSim.
Realized later that they were not the same.
Then came to realize the conundrum I'd created for myself.

Aw, don't worry Simon, your build is safe. He thinks he needs those fancy composites and exotic materials despite my repeated pleas not to use them.
