WNW session at Pt Chev. Tested Dan's old 2013 JP 1X 59 cm x 236 - 91 litres slalom. Had mast track near the rear and had to tighten footstraps. Never really got it cranking, although felt as if it  might have a good top end. Felt a bit underfinned with 30 Venom. Did not  plane as early as Falcon 80. will try again tomorrow at Bucks if SW. Seemed to eat the chop!!
