If you're looking for a diverse fin set that is springy and responsive but still holds well when you're riding the rail, look no further because the Futures F4 Blackstix 3.0 Small Tri Fin Set is perhaps the most well-balanced thruster set on the market. The unique V2 Foil blends the traditional V Foil and Flat Foil styles to generate propelling speed while still allowing for a controlled "WHAPOW" throughout turns.
Blackstix Construction – Blackstix construction has a flexible Carbon Fiber tip that loads up and releases energy for generating speed when you need it. These are the lightest fins in the Futures line.
Side Fins – Height: 4.37" / Base: 4.22" / Area: 14.22" / Foil: V2
Center Fin – Height: 4.37" / Base: 4.22" / Area: 14.22" / Foil: Symmetrical
Symmetrical Foil – Even water flows to both sides of symmetrical foil fins for a fluid consistent feeling that is predictable in all conditions.
V2 Foil – A V2 Foil is a V. Foil and Flat Foil blend. It takes the best speed generating attributes of the V. (at the base) and transitions into a flat foil in the tip for a controlled release in critical turns. Try the V2 foil if you are transitioning from flat sided fins. The benefits of the V. foil base will be noticeable but the change for your muscle memory will not be too drastic.
Ride Number 9.6/10 – Ride Number is all about how your equipment feels while you're surfing. Now you can choose a Speed Generating Feel that is springy and responsive by picking a fin in the 10-7 range, or a solid, engaged, and predictable feel from the Speed Control category rated 4-1. For a Balanced feel try a Ride Number of 7-4.
