Maybe good, maybe bad...

Whoops, forgot to fill this out so my memory is a bit vague, but I remember it was light and I didn't want to risk the 21, so I went with the 15 to see what it's bottom end was with the foil. Not bad, but the problem is the kite isn't swift enough to work to build speed. Seems like the 12 is the limit for that, and if it's lighter then go for the 21 and change early...
