I guess the plastic wedge is just for placing in a cut to keep the cut from pinching?

Never broke a Pillar double taper or Madsens orange wedge until below zero. Then we switch to Pillar super tuff's, never broke one at any -zero temps.
Stacking 3 in the winter is a little sketchy, they like to pop back out.

Hardheads were shattering in the cold last winter for others. I don't use them.  Guess they are a summer wedge.
