Yes, that was also my guess. Most of your competitors use small side fins (e.g. Goya Custom Pro Surfwave 78: side 10.0cm, center 17.0cm; RRD Hardcorewave 78: side 10.0cm, center 16cm; Tabou Da Curve 76: side: 10cm, center 16cm), so, for the Choco 9.5cm, center 18.0cm seems consistant.
2 more questions:
-Regarding the shape of the Choco 9.5 (top flattened), is it appropriate to use them as side fins in thruster mode or should I expect something strange?
-On MFC website, there are many option for Wave fins (TF Thruster; VR Trifin thruster) and Freewave fins (TF/FW Trifin Freewave). I'm lost!
My regular practice with this Grip will be bump and jump in strong wind but small and short waves (max 1.5m). What to choose for the best for me?
