I have the Sculpture Swing.  I also had the Frattini Dyna-Maniflex replica.  At first I preferred the Frattini because it was "traditional" and tradition always ranked high with me.  At that same time, I was able to borrow the new Begali Swing from Ulrich, N2DE for about six months.

  Well...the Swing really started to attract me more and more.  For one thing, it doesn't ( "can't") chatter.  It's adjustable well beyond any other cootie I've had the chance to play around with.

I began to use it more and more.  When I couldn't hold out any longer I sold the Frattini and bought my own Swing.  RBN doesn't seem to have any trouble copying my fist and I haven't received any complaints lately from anyone else.  It's a beautiful work of art with a substantial heft.

It's on a glass-topped operating desk and there's nothing underneath but the glass.  I'm a bug slapper but the Swing refuses to move.  In fact, I managed to break the original contact arm on Ulrich's Swing and Piero sent a replacement arm of larger diameter.  I like to think that was my contribution to the present sturdy design.

I love the Sculpture Swing and I'm sure my cootie fist has been improved thanks to its remarkable engineering. 

Here's an old Youtube video I made back then.
