I want to share my latest experience on the efoil build journey. I have been using gong curve 1400cm2 xl with xxl stab with good results. I just now tested the curve L 1200cm2 with the extension on xl 46 stab. WOW what a smooth easier ride!
The turns are more fluid and for me 1st time I could do ripping toeside turns. So now I want the M wing to try. The speeds I was running happy at 28-30kmh very smooth feeling. On the 1400 wing it is proportional slower but not as smooth somehow.
Here is a pic
