did some one try to add battens or use some braidels ,or.... to modify the 13.5-ar5 ,
iknow that the cabrina have some modification in http://www.kitexite.come

I improved my ARX 15.5 with battens at the tips, but could feel much of a difference.
The best is to use shorter lines.
Using the 15.5 ARX with 20m lines makes a lot of fun. Try to use it with 20, 22.5 and 25 m lines to find out the best handling for you.
Bridles I never attached to it, but I don't like bridles at all, maybe that's why.
Maybe someone else has good experiences with bridles?
