Whats your thread of choice when sewing 1.1 nylon?

So I have read several places that you should NOT use cotton thread, since it will soak the moisture, it also decomposes faster than the nylon and its just not as tough.

I also saw someone selling special extra heavy duty thread, but what are people really using?

The 1.1 ripstop is in the mail. This will be my 2nd hammock. I made one, 2 years ago, before I knew about this great forum but its only about 8ft long, so I am giving it to my 4 year old daughter. We plan to hang at the local campground soon (been practicing in the yard).
