Here's a solution I came up with for smooth control for those cinematic moves that make your thumbs cramp. Take some half inch foam and cut out a 1 1/2" circle, poke a hole through the center, remove thumbsticks and insert through the hole and reattach to your controller. This provides just enough resistance without restriction movement to the furthest limit of your thumbsticks. I think you're going to love how it feels.
