Exact Indoor Plywood Type to Buy

I am puzzled at the exact choice of plywood. We need about 10 sheets.

I understand the AC type but am not sure if:

  • the type of wood matters (Birch, Oak, Maple)? Are some harder than others?
  • should I be getting it at HD/Lowes or does it make sense to go to a lumber store at that quantity?

Here are the two options that I couldn't decide between today:

Thank you in advance

FWIW I've used the first style to make the volumes on my wall and have had zero problems.

Save your money. CDX is fine. AC is just a higher grade on one side, it that matter to you. Same core, same # of layers.

Thank you, wonder if that's the case for whole size sheets?

My largest volume is a triangle with 30ish" sides and is attached to the 45 degree portion of my wall.  It sees significant stress and it feels solid after 18months of use.  I also drilled a t nut grid into it and don't currently have any screw on holds attached to that volume.

Guideline #1: Don't be a jerk.
