I was wondering if anyone could advise: I have a quiver of 5, 7 and 9m 2010 C4's, and a well used 2008 12m light II I am only interested in wave riding with surfboards, and find the C4's great for this. I did own a 2010 10m Catalyst but sold it in preference to the C4's I also owned a 2010 10m C4 which I did not like for some reason - so swapped it for the 9m which is a fantastic kite, especially on short lines. (anyone else find the 2010 10m a bit strange?) I weigh around 75kg and find the 9m C4 is just about ok with lots of work and walking back upwind down to about 12knts with a 5'10" surfboard, as long as the wind is not too on-shore and the shore dump is not too big. I need to replace the 12m Light as my low wind kite, ideally with a 10m. I was wondering if anyone knows how much better the low end a 10m Reo would have over the 9m C4? I don't really want to go for another 12m kite.
