I like symetry, for the most part. I buy things in pairs and I prefer to display things in pairs, if possible.
Two acrobats is way cool! I would like to add two or three more to my arsenal, just so that I know I would have parts to keep at least two alive at any given time. LOL
This thread reminded me that my older Acrobat needed a good cleaning. For a while it's been stopping in between gobo patterns when I run it through scenes quickly.
All I can say is that some compressed air and a little bit of Windex can do wonders. Even the thinnest layer of baked-on dust is enough to make the patterns appear dull. After a half-hour of work, they pop like new.
