Try skim boards if you want to get going in the lighter conditions.
While you may not be boosting and doing great airborn tricks (nobody else is either) there are shimmies and olleys etc. All great fun.
The main thing is you are out on the water having fun, while the others are struggling and doing the walk of shame.
I ride a North Skim Fish, but there are other brands out there that probably do similar. I have North Rebel kites, but none bigger than a 12 meter, and I have lits of great days in light conditions, and it rockets up wind.
Also a guy I kite with has a North Pantom, (strapped twin tip) basically a barn door. He's a bigger guy, and he gets going a lot of time in marginal conditions, on a 11 Meter Rebel. Big board little kite.
Have fun!!!
