Over the time I have had my 6000 things have stretched a bit "down below" and I was able to move to the second smallest ring. Just recently, however, this broke and I was forced to go back up to the middle ring. The smallest ring is just a little bit too small for continual use. Would anyone have the second smallest ring that they would be willing to swap for either the largest or second largest ring as I will never use these. UK would probably be best as it would be easy to post.
