the HYAK is basically the GNU Carbon credit not in asymetrical
This is the most affordable board you can get in the mervyn range. but don't discount it as a top board. iits still a rocking awesome board. if anything its the GNU skate banana,
its a fun board and great for begineers but pros will like this as well because its fun board.
check the review. (its 2016 because i couldn't find the 2017 one) but it would be the same.
