FCS for mini simmons type board?

After nailing my first board with the help of all you swaylockers a friend of mine wants me to try and make him a mini simmons type board,

 

Most of them I have seen have fin boxes for the centre fin and I dont have a router so I was wondering if i could just do one with fcs, would some large fcs fins like GR’s or G8’s do the job?    We want it to be a performance board and he doesnt want to consider a quad set-up in case it loses some of the directional looseness if that make sense.

 Also would a spiral v bottom contour be ok for a mini simmons? I know many of you are into hulls but the plan is to make it feel as much like a performance shortboard as possible while still maintaining the positives of mini simmons type benefits.   I remember that I used to see some guy riding a mini simmons type board at my local break and he was doing such awsome turns like he was riding a regular shortboard but maintaining the speed over flat sections and the obvious paddle in advantage.

 

 Here is a photo of my first board, turned out pretty well I think due to the months of ‘mind shaping’ and getting good advice from many of you, Im stoked with the board and it rides great so a big Thank You to everyone.

 

 

You’ll get much more turning ability out of your mini if you just pull the tail in a bit. I feel like taking away the hull and adding concave would really take away the planing ability of the mini sims. I can really feel the difference when i step off mine onto a shortboard or something, it just bogs on the takeoff relative to the mini

 

As for fins, a quad (or maybe twinzer, never tried one) would be the way to go as far as performance…with the fins as far apart as they are, i feel like the GR’s wouldnt be big enough…if you’re really pushing through turns, the outside fin is basically out of the water, so for hold you want the inside fin as big as possible. A quad or keels would keep more fin area in the water during turns. 

 

But hey. Go with your gut. You may be onto something.
