Monty, for my spot you would have to have a 10m for the summer winds...I have the R4 18. An option is to add a 14R5 and 10R5 - make sense? OR just go to the 12R5 and have a two-kite quiver.
Foxi, R05 has NOTHING to do with R04. Nothing.
Today i had a great session on my faithfull Nemesis 10m with 23m lines (34 to 54 km/h winds). That is definitly my prefered kite . Will not sell it for sure. I can't explain why it feels so good... Maybe because it is a 10m...
