Only a couple to things to say on this one.
1. They Listened
2. Entirely new design and development team from the time you refer too.
3. Great advancement in the materials being used for the actual production of the sails. Again, great advancements have been made on this front in recent years.
4. No redesign on rigs and components, including freeride masts intended for recreational sailing for several years running. (other than specialized race products as needed of course)
As far as warranties go; please refer to my earlier posts.
