How it surfs
The Monsta 10 sits between the Happy Everyday and the Ghost on the performance ladder. Reviewers describe it as the everyday board of choice for surfers who prioritize turns over wave count — the extra rocker and pulled-in nose reward committed rail work.
In HYFI 2.0 the board feels notably lighter and livelier than the standard PU option, and multiple reviewers rate the upgrade as worth the price. In small, gutless surf it needs commitment to unlock, which is where the Happy Everyday quietly pulls ahead.
