Jewan, Naish Park for the last few years? Prreeeeeeetty sure that's always been a freestyle/wave kite

but I digress.
No one said that the Dice/Park/RPM etc are the ducks nuts when it comes to freestyle or wave. Sure some marketing hype will but of course it'll say that. Personally if I was riding these kites I would be riding the Park for freestyle and the Dice for wave riding. They definately have their strengths and weaknesses.
Sorry Drury but I disagree 100%. 24m will be absolutely fine on the 10m. We have been running the Dice on 19/22/24m lines both Quad & 5th Element over the past 12 months and depending on your riding style, conditions, preferred feel and personal preference, will depend on which length you go.
We generally push the 24m lines towards riders who have the 10m as their one kite as it gives good all round performance. The 22m lines I find more fun when it comes to unhooking and wave riding as there is a little less lag to the steering and a bit more of a direct feel on the bar. But that's just me. It's also nicer to throw the kite around in the waves on shorter lines as there is less wind window for the kite to fly through as you throw it from side to side.
10m & under the 22m lines and 11m + up go the 24m.
