here there are lots of days where waves are 2ft tall and I wonder if the hokua will have enough volume for this days
Actually, for slow small mediterranean waves, you do not need volume. You need a flat rocker to get speed, a wide tail for the wave to lift you, and the thinnest rails you can get to be able to have fun turning it. Better get the volume by the width rather than the thickness.
The 8'11" Drops Vulcan is a really good light fast "fish" board for light people on slow waves. F-ONE PROSHOP CENTER in Valencia is a Drops Dealer, maybe you can test one there? (or other models)
Otherwise, Jimmy Lewis Kwads seems very nice too, and are very stable for their size.
PSH boards are also nice in med, due to their fast rocker (flat in the center)
