When I owned a SW 9, I had first a Boxer SLE 12 tunned in 1:1 mode. The SW9 bar presure was much much much heavier than the Boxer SLE 12, and have backstalling tendency in the low end of itÃƒâ€šÃ‚Â´s range.
Then I decided to change the SW9 (2006 model) to the 1:1 mode using the 2007 shockbar. Now the kite is well tunned, faster, lighter, and works well in the low end of itÃƒâ€šÃ‚Â´s range. I can now stear the kite with only one hand in the center of the bar... Just the perfect kite to me at the moment!
Love to try the 2007 shockwaves... but no one here!
