Which of these two Veritas straightedges would you use for the setup a Grizzly G0500 Jointer (8" x 75 1/2" bed) and a SawStop PCS31230-TGP252 (52" right of the blade: 33" x 85 1/4")? The 50" Aluminum (accurate within .003 over the entire length) or 36" Steel (within .0015)? Assume both are sitting on the shelf, but you can only close one.
