Here in Northern VA, hurricane winds aren't too common, so I just went with ring shank and a few judiciously placed Simpson Strong Ties. I suspect it's even less of a concern in NH, though winter winds might be an issue for you.

Here in Northern Minnesota they use standard framing nails out of a gun for it. We dont get much for wind unless its a tornado in the summer.

OK thanks guys, yea in NH strong winds are not very common at all. I appreciate the input

Ring shank nails, nailed at a angle to make a X with nails.

I used 16d nails on my 2x4 purlins on our barn with 3 nails each connection to truss.

If I had to to again, I'd use the wood screws, but I'm in Florida and we do have wind.
