Chastity and orgasm denial discussion

Currently, I’m using a CB3000 (older version) and am quite happy with it. However, since the unit is getting a bit aged, I’ve been considering picking up a CB6000. While browsing online recently, I spotted the CB6000S, which looks intriguing. Being uncircumcised makes keeping things clean slightly more difficult. Online discussions suggest that cleaning is easier with the CB6000S because the glans sits closer to the urine exit hole, reducing soiling.

Sometimes there’s a bit too much space in my current device, but when I get an erection, it remains fairly comfortable despite some minor pain.

So here’s my question: what are the criteria for choosing a CB6000S? What would you recommend? (For context, neither my Lady nor I have any interest in metal devices or belts) *edit: Typo fixed; I am UNcircumcised (A)
