Felix - What frame did you use for your Zen setup? Understand the visual impact of the bigger sail and that all the sails have different responses!! I have an SUL for light winds and use it with a 2 wrap frame!! When I fly alone, the 1.5's quicker response works fine!! Don't have a Zen, YET!!! Just trying to get some kind of understanding of why and how, changes affect things!!
As above, Race with 3 wrap center...
