Moving Between Cages for a Smaller Member

I am a guy in my twenties and new to the world of chastity. My penis measures 5.5 inches. Right now, I use a CBs device, but I plan to pick up an HT nub and a cherry keeper soon. Does using chasity cages follow a specific sequence if you want to shrink your member? Also, will jumping straight into a mini cage make the process feel dull for me? As a beginner, I am looking for advice on which devices to use in what order.

Have a good day!
