Yea, you can fly most zeros from just aft of close hauled say 40-50 degrees back to 140 or 150. A-chute will be very slightly (in cruising terms) faster on the deeper angles, but the zero is so much easier to use. For cruising they are very versatile sails
, for racing
they have a narrower window where they are the best possible option. Typically for cruising you want them cut a bit deeper, with less mid-girth than a racing
If you wanted to run it at 160 . . .you could pole it out the other side.
