what is the best truss
-
Triangles, basically. Triangles are the basis of good truss design, so the forces that it resists are transferred to individual members rather than to their joins. If you need to hold up a vertical lattice of members (like a wall of 2x4 studs in a square frame, standard wood/steel framing techniques) against sheer forces acting across the top beam, the answer is to provide a single brace that runs diagonally from a top corner to the bottom rail at about a 45 degree angle, attaching it to all the studs it crosses, thereby making at least one triangle out of your rectangular frame..

I don't truss a truss but may occasionally trust one if it is in the roof over my head.
