WAG Shoulder Flexibility Rod Stretch, Difference Using Wooden Bar Rod or Towel Rope

[melissaallen59425]

Whats the difference in doing the shoulder bar dislocation stretch with a regular wooden rod vs a towel/rope? (Note: I know the second picture is using a towel, but I use a rope and pull it wide tight).

The hands and wrists can move and rotate differently with the rope / towel. Not much is different really.
