Which one would work better in light winds (I´m 77 kg):
12m C4 kite and Nobile XTR 143x48 board, or 132x40 board and 17m LW kite?
So I already have C4 12m and 132x40 TT, but thinking should I get a bigger board (only TT) or 17m LW kite (wife doesn´t let me buy both of them

...).
2011 kites that are on my mind: Core Riot 17m, Slingshot Turbine, Epic Renegade Infinity
Many thanks for your help.
