How it surfs
Where the Rad Ripper wins is off the tail. Reviewers repeatedly note the transition from paddle to top-turn snap is more shortboard-like than any other board in its class — the reason it out-sells most of Lost's grovelers.
The trade-off is that the wide nose can catch in steeper, more critical drops. Once the wave gets much bigger than shoulder-high, most reviewers move to the Puddle Jumper HP or a proper shortboard.
