Carbon or Non-Carbon for First Marathon

Developed some calf/achilles soreness over the 2nd half of my training block, I don’t expect this to keep me from finishing my marathon training. Working with a PT and getting some strength training done.

My question is, with a calf and Achilles issues 3.5 weeks out from a marathon, should I press through with my original Carbon shoe (NB SC Elite V5) on race day or should I switch to something with a bit more support like a Superblast 3 or Megablast? I have over 100 miles on both my Superblast and Megablast and none of them have given me issues thus far.
