which sail would you get?

[Acadia]

Hi,

My boat only has 2 sails, a main and a 110%. I would like to add a sail to the inventory and I am trying to decide between a Genoa (140% to 150%) and a Cruising Spinnaker.

Most of my sailing is on Tampa bay and the Gulf, so many light wind sailing days mixed in with strong wind from when the fronts blow through.

Eventually I will get both, but can't decide which to get first.

I'm a novice sailor so interested to see what some of you experienced people have to say.

thanks
