Yes I ordered an 8A on advice from Lori when the device in stock #5 we purchased was to small a diameter and could not be removed without help from hospital emergency!!! The 8A was not for me as it was to open in design even though 2 extra bars were added. My keyholder always wanted the #5 (closed shaft design) and used her vibrator to see if the 8A was affective, she took me right to the edge and stopped and decided that I would be able to stimulate myself enough to come. The 8A was sent back and a #5 was built to our specifications. Locked up ever since!!
With lori being able to make things custom I would think you could ask for some additional bars. I was inquiring about the 8a a few days ago and she stated there are going to be making them in titanium as well. I would think it could be light enough you might forget you were even wearing it.
