Just got back from the NAMM show. Conn-Selmer was showing off the new Avanti flutes with the new Straubinger Phoenix pads which are standard on Avanti for 2009. VERY impressive. There is a noticeable difference in the performance of the flute.
They were also showing off the new C# trill key for the Avantis.
They are different then typical Staubingers because they do use a cushion felt that wraps fully around the exterior edge with a skin layer rather then being put inside the edge of the synthetic material.
This should give a much more traditional pad life compared to standard Straubingers. I have a diagram of the new pads on that page.
