The Black Diamond is an excellent all-rounder. It has the right area and volume under the chest but not much in the tail, making it great to manoeuvre. It paddles exceptionally well and is fast off the front foot.
This board is easy to ride, gets you lots of speed. It is my second Black Diamond, the first one being a 6'0 PU. The eps version is a bit faster, has more manoeuvrability, but need cleaner conditions to perform at it's best.
I haven't found a better all-rounder board, that my 70% of the time go-to board.
