Doug s Miami

Just met Severine team rider Bjorn in St Barth's He suggested I get a Futura board for how and where I sail in Miami. My question is what size and carbon or wood? 131 or 141? I run on a 145 + 5.7-6.3 but want to dial things up. I learned 10 yrs ago on a large board with a 7.5 World Sail with cams. I'm happy just to cruise between Miami and Key Biscayne dialed in with some good music even if it's only 14-16 - which board and what sail is going to do the trick?
