Had a couple of sessions today with my new 20m lines.North have designed there kites to be used with 25m lines.
Used the 9m this morning in the waves in 23 knots and the kite felt brilliant,very responsive on these shorter lines.Had another session in the arvo as the front got closer and the wind was stronger 26 knots and gustier and the 6m rebel was super reactive,so easy to put the kite where it needed to be.
If you have tryed the Rebels before and found them to be slow try them on 20's you will be surprised.
If your in Gero go see Kym at GSS and try out his demos on the 20's

Yeah, I prefer the 20s for waves. I've got a 25m bar and a 20m. I always take both with me.

Or get a faster kite
