Mature Metal discussion

Hello, I usually wear a HolyTrainer v2 small with their oddly shaped 36mm ring. It fits nearly perfectly and is as comfortable as you can get with these devices. I’m thinking about picking up a Jailbird because Mistress likes the look of metal better than plastic. I’ve tested several inexpensive Chinese cages; they function well enough but aren’t quite as comfy for long-term wear compared to the HT. I typically go with 40-41mm rings, and when using metal cages, getting the ring size right makes a massive difference in how comfortable and usable it is. If anyone here owns both a JB and an HTv2 small, could you please post your measurements for ordering from MM? I figure the oval rings will be more comfortable, and maybe the double-ring model feels most like what I’m used to with the HT firm fit?\nAll suggestions are welcome. -droog
