I'm going to finish a board from a blank I made last summer. It's a 7-2 copy of a Naish Raptor.
I'll use it in mushy wind waves and perhaps I'll take it to someplace on holiday and surf small up to head high waves.
My plan is to make it a quad, using future boxes because I have the one-pass installation kit and am familiar with the installation.
I'm trying to save some money and use some fins I have on hand, a pair of twin keels, these K2 Or these Aipa below. I'll add some rear fins I'll have to buy.
Question : is this workable? What rears should I buy, any large quad rears ok? I'll use this kind of fun placement : close to rail, tightly clustered. Sound ok?
Is it at all possible to just use twins alone?

And lastly, I'm considering making the nose more like the board below, instead of the square Raptor. Any thoughts on this??
