You should probably use screws instead of nails as well.

Truss top cords are only 1x2 and will readily split if not pre-drilled/use of proper fasteners.

Absolutely agreed. In this case pilot holes are your friend. Also not a bad idea to fill the hole with sealant before you drive the screw in.

1x2? Yikes. Pre-drilling was always the plan followed by a piece of Eternabond and plenty of Dicor. You have me questioning my fasteners now, I was planning to use 1/4” lag bolts.

Self-drilling structural screws. NOVA is a good brand.
