I am surfing normally fast beach breaks in the southern part of Brazil, Parana and Santa Catarina states, I have surfed for 5 yrs now, coming from a pro windsurfing background, hence not that windy where I live in Brazil, so I changed to surfing... ' The King sport' :-) anyway, I have moved from a 9 foot long board down to a 6,6 performance 2 yr ago, 6.6 19.9 2 5/8, custom board from a local shaper (PU) was not a big success, as I needed more volume/stability, I then surfed on a 7.0 fun for some time and since April I have been surfing a JS Blackbox in 6.2, 20 1/2, 2 5/8 34.7 liters vol. However I still feel that I need a bit more volume, I am 184 cm and 95 kg and going towards 90kg, 35 yrs surf every weekend and all holidays. I feel that I am kind of stuck with the 6.2, my paddling is strong, however I feel that I am kind of dragging the board along, I can drop into waves even the fast beach breaks, however I am often late on the timing....some of my ' 75 kg' surf friends, says that it will help if I got a longer board and more volume to allow me paddling into the waves earlier, and suggested that I got a ~6.6 , but as they also said the issue is that the waves are quite fast...so I dont want to go too long either....the surf is around 2-5 feet, occasionally tubes.
Now then I came across Firewire and the dominator and it seems to be my salvation :-D, my questions to the forum is, will a 6.4 be the right choice for advancing my surfing? according to the volume calculator, I should be between 35.5 and 46.2 for an intermediate, which match the 6.4 41.5 liters. maybe a silly questions, however do you think I will be able to 'feel' the additional volume of the Dom going from the 6.2 Blackbox 34.7 to 6.4 Dom 41.5? Sure its a completely different outline...or should I go even bigger? or would another board from Firewire be a better solution? I am just into flowing turns, nothing fancy, just started to get the feel of it....
I appreciate any inputs, thanks a lot.
