I sail a Nacra 5.2 and am working on turboing it. The next step will be adding a spinnaker to the boat.

I need to know what spinnakers I should be looking at. I want to get a used on because I have never flown a spin before and I know I will tear something up.

The mast of the 5.2 is around 28 feet long, I have the freedom to attach the spinnaker anywhere on the mast since I am designing the system.
I was thinking that some of the f18 spins might work, or maybe a f16 spin.

Does anyone have info on a good used spin that might work? If so pm me and just respond here.
