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.



Typically hurricane straps add tremendous strength if you are building
for wind storm resistance.



Look up "fasten master" structural screws. They are approved for a LOT
of general construction use - and their "timberlok" screw can be used
in place of hurricane straps to fasten trusses to double top sills -
as an example - replacing the tiedown strap and 12 nails with ONE
fastener.
