Used to be that framing had to be toe nailed...
Now I see nails used from top and bottom sil to studs. Not as strong.
The toe nailing really locks it in from both sides.
straight nailing will not withstand storm forces as much.
But then again, most roofs will easily lift before the framing gives.

That seems a little strange - what's the rational given, if any?

Nails generally have a greater shear strength than screws, thus the
requirement in some areas are very specific as to the nails used, their
size, makeup, and nailing patterns.

I learned the hard way that any carpentry (as opposed to ww) work I do,
someday I, or someone who comes after, will have to take it apart again.
I use screws for all that now.

A straight nail driven into end grain has about the same holding power
(in tension) as yesterday's chewing gum.

When it is nailed from the top plate or sill into stud endgrain, it suffices since
the roof holds them together - the nail is to keep the stud aligned, any forces
will be perpendicular to the nail.
