I'm wondering about the durability difference between the race-specific kites. If I purchase a used one, will it lose performance over 1-2 years, or the material degrade so much that it rips easily, or loose airtightness.
If the bridles are really old and used / assymetrical (no re-streching possible anymore), does a complete bridle-system change solve all performance issues?
Which one is the most durable? I'm thinking about R1V2s, Diablo 3/4, Sonic Race/VMG, Peter Lynn Aero v2.
Also, easier handling is a preference.
