After thinking that C kites were crap for Tassie conditions, I am now changing my mind after flying a demo C4. Seems the hybrid-C is working out alright in the gusty winds we get.

Can C4 riders or anyone who has ridden one please help me narrow down kite sizing. I have come from GK Trix's, and basing my ozone experiences on flying a 12m C4. My stats are:
Weight: 73kg
Board: LF 135 concept

Kites will be used for unhooked freestyle, waves, and boosts. The kites I'm needing to replace will be a 12m and 9m GK Trix, to cover windrange from 12-30knots, or as much as possible of this range. Have got a 7m for the big stuff .

My experience with the 12m C4 has been really good in the higher part of the windrange, but lacking grunt down low when I would normally be ok on my Trix. Am wondering if the 13/10 C4 combo would work for my weight to get that extra grunt, and if there is much of a difference in windrange/grunt when comparing the 13/12 C4 and 10/9 C4. Any experiences with how the meter difference affects hold down and unhooking would be greatly appreciated!
