Chastity device discussions and reviews discussion

If you’re considering permanent chastity, which material would you pick? I was looking at the CB6000S but:

1. It seems too large for me.
2. Too bulky for long-term use,
3. And it’s plastic. So now I’m eyeing the Master Series Exile because
4. It’s metal,
5. Fits properly with a 1.75-inch length,
6. Being smaller makes it easier to wear long-term and hide,
7. Comes with three ring sizes. What do you all think? Does my logic hold up? Do you prefer metal over plastic? What device would you suggest for someone with a flaccid penis of 2 inches?

Definitely go with metal. At that size range, the weight isn't really a problem either. The CB series is pretty poor quality, though I'm not sure about the other options.
