Difficulties with wearing a device? discussion

I’ve tested out several devices from friends who upgraded their CB6s to Holy Trainers or switched to metal, and I find that the standard 50mm (2-inch) rings are just too small. My flaccid size is about 2 inches, but a hard cage isn’t an issue; it’s really all about the ring diameter. Does anyone know of some options with larger rings that aren’t overly expensive?
