Difficulties with wearing a device? discussion

I spent years hunting for a device suitable for extended wear, but ball-trap models caused too much chafing and sat too low, while my unique anatomy made PA devices unsuitable. I finally decided to order a full belt from Behind Barz. It’s been on in intervals lately, and I suspect it could be a long-term solution (!), though I have a few queries for fellow users…

1. Do you wear the ball ring? What’s your reasoning? Personally, I found it chafed more than the ball-trap types did, so I’m puzzled by its purpose since it doesn’t appear to offer much utility.
2. Is the rear rod worth using? It feels like it improves security by pulling the cage tighter against the skin. Still, the idea of managing a bowel movement with it in place gives me pause. Can it really not be shifted aside…?
3. Am I alone in feeling that you can slip your fingers under the sides or top of the cage? You probably can’t do much with them there, but I assume this isn’t supposed to happen..?
4. How precisely should the waistband sit? Do you find it hard to fasten? Is there room for a finger? Just wondering—security-wise, I don’t believe it matters too much.
