I had been thinking along similar lines but havent had time to implement it. Only concern will the ring break down over time now that it has been cut?
None that I can find (nor any reason to think there might). That's why I made 'an ugly one' after the pretty one worked well. I wanted lots of rough edges that might tear with use. Careful inspection doesn't find any and I'm using it as much as I can...... No sacrifice is too much to ask in the name of Science you know.
That's why I was kinda happy when I could 'afford' to send each guy four. I figured one to butch up, one to try and abandon, one to loose outright and you'd still be in business?
