The mainsail is a bit too flat on the top to my taste, but otherwise very good. This G3 bi-radial cut is as WB-Sails offered it - works very well, no extra stretch at the foot.

Flat top can be fixed by changing the top batten to softer one. This is typical case. In light wind a softer batten is needed or you need to adjust (increase) the pretension of the batten to make it bend more. In heavy wind soft batten easily makes the top too full. One soft top batten has worked just fine to me.
Summary: Top full batten should be trimmed or changed according to each wind condition.
