North Sonar Aluminum Foil package with an 85cm long mast. This front wing option is great for kite foiling in light winds or wing foiling in stronger wings for prociecient riders. The 850 MA V2 front wing option will give you great bottom turn feel with great heel to toe pressure and feedback while still providing good glide performance. The MA850 V2 is fun and efficient but not as glidy as the SF stuff, plenty fast.
