One of my favourite boards a the minuet is the "Evo IQ". It came out in this summer and has been a huge success, due to the fact that you can sail with one or two fins depending on your style, preference and weather conditions.
The board is made up of wood and carbon which makes it one of the lightest board currently on the market, in addition to this it is incredibly strong and perfect for freestyle.
How ever this board is pretty good, it come with a pretty high price tag starting with the smallest version at £799.00 (inc. vat), but if you are a keen free style windsurfer this board could be the perfect one for you.
