I heard that the foils will be a lot better once the new carbon mast is out as there were issues with the current masts.
Interesting! Do you know when those will be launched and if there will be a new aluminum version? i currently use the s glide 800 and i do have Mast ventilation issues. At least that's that's what I believe it to be. I unfortunately don't have any foils for comparison. It could be also my riding style cranking to windward quite a bit.
