I started to see Firewire boards in surfshop in the heart of Encinitas and once in a while in the water about two years ago. Now that I am back in Florida, I don't see any but that is about to change as Lost is going to partner with Firewire on at least two models.
Yes they are more expensive than regular PU foam board but oh man what a difference in the water. I am far from being a pro but I could feel instantly the difference: it is lighter, more responsive and it simply feels better under the feet.
Until you try, I don't think you can be convinced by words so here are my additional two reasons to switch to Firewire in addition to the performances:
-EPS foam, Epoxy, balsa means a lot less pollution during the processing of a surfboard: not totally green but it is a huge step toward the right direction. and remember ocean is given us so much that is the least we can do.
-Much stronger so the board is going to normally last twice as long, which means it will pay for itself.
I would say the partnership with a brand like Lost is going to be really helpful to popularize the technology.
