Try putting these under the feet you will get much more movement with less pressure needed.

I appreciate nudging and set tilts to allow for it and even a well executed death save can be done but a sloppy one gets a tilt. That encourages players to learn to use finesse or tilt. I of course respect everyone rules at their place. To me pins are designed to have the player interact with them nudging adds to the experience and enhances a players skill set.
