iSonic 101 or 111?

[GFB]

Hi Kevin, I am not sure with the right size for my purposes. I am 175 cm tall and weigh about 80 kg. I use most frequently sails from 5.4 to 6.7 and a JP Freeride with 100 liter. But my JP sink. I had no opportunity to test the both iSonic. I would prefer the 101 with 63.5 width. Will I sink with the 101, if the wind asleep? Many thanks and best greetings
