It delivers a lighter, stiffer and more direct feel than the standard construction, without moving to the price and more specialist nature of the D\/LAB. In 4m, it is an excellent choice for stronger UK conditions or as the smaller wing in a two or three-wing quiver.\u003c\/p\u003e\n\u003cp\u003eThis wing has been part of our demo fleet and may therefore show light cosmetic signs consistent with demo use.

For an average-weight UK rider, it makes an excellent partner to a 5m or 5.5m main wing, giving useful overlap as the wind increases.\u003c\/p\u003e\n\u003cp\u003eLighter riders may also find the 4m becomes one of their most frequently used sizes. Heavier riders are more likely to use it when conditions become properly powered.\u003c\/p\u003e\n\u003cp\u003eIf you are still learning your first waterstarts and sustained foil flights, a larger and more forgiving wing will generally give you more time on the water. If you are comfortably foiling and want a wing that remains controlled, responsive and easy to move around when the wind strengthens, the 4m SLS makes much more sense.\u003c\/p\u003e\n\u003ch2\u003eWhere does a 4m fit in your quiver?\u003c\/h2\u003e\n\u003cp\u003eFor many riders, the 4m is best viewed as the high-wind half of a two-wing setup rather than a single do-everything wing.
