Shaping a Semi gun, cad file attached. Please give feedback

Hi Everyone, I have designed this board attached because i have surprised myself with making bigger waves than i expected on my 6’3 round pin this winter in cape town. ( and its awesome) i however, want to do this with a little more ease and more control. I would also like to do it on even bigger waves, say up to maybe TOH. I want it to perform around with drive, turns and hold in hollow sections. I am 6’2, weight 90 Kg and wear a US 11 shoe. Can anyone give me feedback? Specifically on the rocker as well as outline. The rails are going to be very forgiving through most of the board but hard in the back 20inches or so. The other question is, has anyone got a good fin template for me? I want to use a single fin box and then a quad setup, ie 5 fin setup. The specs are: 7’6x19 7/8’x2 7/8" with the nose rocker at 5 5/8" and the tail 2 11/16" the nose is 12" and the tail is 13 1/8". Any input would be much apreciated. I like it as a pin tho
