Depends what you want it for and what sizes.
This year I opted for the WC IS121 mainly because thats my light wind board which I use for racing. The IS94 I stuck with wood cause its used in higher wind and choppy conditions so abit more forgiving. Ive had the WC121 out yesterday in very light conditions maybe 8-10 with an 8.5 so I was supprised to be planning.
It defiantly planes abit earlier compared to last years 122.
So for light wind yer I would concider the WC if you can get one
