Don't forget the snivel on opening with a 9 cell high performance canopy cuz if ur worried about lines twist also think about the 800 - 1000 feet you loose on opening.. Getting use to my Katana 150 from a Sabre 150 was a big difference. It is recommend to go for a PD Storm 7 cell or something like that which i may be doing in the future, but the flight characteristics of the Katana are addictive.. Double edged sword lowered more predictable opening with a Storm or open high and hang on with a Katana..
