By far the most enjoyable fin i have used on a longboard. Plugged it into my McCoy 9’2” Malibu XF All Rounder. Honestly - the perfect combination for this mornings 2-3 foot beach break. Fin and board combo provide stability but also total control on the face, fast, manoeuvrable, great speed and trimming, good for floaters, gliding, turning or gunning. Really pleased woth this purchase and has become my all time favourite fin and nee benchmark against which all other fins will be measured. Price and customer service from Natural Necessity were awesome. 👍
