I always like to check out the JP board bag sizing for the coming year as it usually has models which have not been put on the website.
JP Slalom VIII Range
I am pretty sure there will be a smaller size also that is not added to the small board bag list:
It appears the larger boards have been resized:
The 76 is now 78cm wide.
The 82 is now 84cm wide.
There have been other leaks on the web but this is on the official website;)
