I have the 5.8 as well

.No grip issues on the pad although I would like to have a non slip paint on the nose for when climbing up (I Probably ad Hexatraction soon).
With a Go foil Maliko200 and 188x95kg and learning it isnt as stable as a supfoil board like the JP 7ft, but I,m getting more and more used to it. Slogging is is like sailing a windsurf waveboard when not planing, too small to be confortable, but mannagable as log as you have a little momentum. Mastposition with the M200 seems to be the best just BEHIND the mid. Probably that is due the different foil. With the mast all the way to the front I need to go with my toes over the edge of the pad when powered up. When flying I really really like the concaved deck. I also tried the Starboard 6.7x28x115l with flat deck but the main reason to buy the Fanatic was that that deck felt soo much better.
Right now i,m on holiday. When i.m back I will put it on a scale, but for its size it is heavy compared to a wavesailboard with 104l
