The choice of light air sails would be based on your confidence levels. If your used to flying spinnakers short handed then that's a good choice as you have quite a wide range of angles in lighter air but if your not that confident maybe you might be more comfortable with a real light reaching sail that can fly with its own wire luff.
If your sailing in trade wind
areas then a double headsail rig is a nice way to go and this is using white sails that are much easier to handle. I think the main thing is chose something that is easy for you and that way you'll use it. Personally I'm very comfortable flying a full racing
chute with just the 2 of us but my favorite sail combo in the trades is 2 headsails raised together in the double luff grove both poled out. If the breeze starts to freshen then you can furl them both in a bit simply by easing the poles forward and furling
some of the sails in. When the air is real light furl both sails until they are board flat and often they will keep you going better than a spinnaker
. If a squall is unavoidable ease the poles forward and furl the sails down to a scrap each. You can also adjust the sails from a run to a shallow broad reach by pulling one pole forward a bit and easing the other. Nice easy way to go
