RE: 4.0m wave board
Can you tell us how you like to sail on your two different boards, the PA 80 and EVO 74? Does one of them suit your style and preference better than the other? What do you like and not like about them? And in relation to that, how do you want your 4.0 sailing to feel?
Both PA74 and EVO 70 are very valid options which will rock at 4.0 for you and still not be to close to your current boards, but to understand which one will suit you the best, we need some more background.
