I have just had a run on my BOXER SLE 15m.. I have both a 2005 12m and 16m Boxer. They dont even compete with the new BOXER. The C's are for sale! I am 90kgs and cant believe how good this kite was for me. 20 knots, easily go to 30.. and probably 15. I waited a long time looked at the switchblade and Shockwave.. This kite has put a smile on my face! The depower is just awsome.
