How does this board perform in small knee high chop and cross winds in the ocean for us normal folk

As I said on another of your topics, this board is almost an allround, performs really well in any condition apart from downwind and surfing in big waves. I don't own a Sprint but many people that paddle with me do and I can see how the board performs well. I saw the video of the 2021 model, it seems they now have a higher nose and more volume on the front, but doesn't seem to have any major update compared with the 2020 model.

Awesome, do you know if the depth of the dig out has deepened as of a higher rail than the 2018 model. Or has the board changed that much over the last couple of years. Only asking as I've a mate who has one and he recons it no different

I don't know, you'll probably have to measure the boards to find out the differences.
