I have a similar question to Frederic. I have the Evo IQ 71 2011 and use it mainly from 5.0 down to 4.0 with single fin. I sail in Athens, Greece where we mostly have mushy on shore conditions with max wave height around 2-2.5 meters, and I weigh 67 kgs. This is my sole wave board. The problem I have on this board is that in over powered conditions the board is great but the moment the wind strength weakens a bit or in between gusts the board almost refuses to plane and it's becoming really frustrating. So I have decided to try my chances with a Quad. Juding from what I want from a board I now know I should have gone for the Evo 76 and not the 71. So based on the above should I go for the Quad 74 or the Quad 77. From what I have read when choosing a Quad you go up a size. So based on that I should go for the 77 but having said that I'm worried about the width of the Starboard Quads because compared to other boards on the market most 75 liter quads are a lot slimmer with width ranging from 54.5 to 56 cm. Your boards are 57 and 57.5 cm wide. My concern is that in overpower conditions I will get bounced around a lot and will not have the same responce as slimmer boards during transitions. What do you say?
