So you still have the DV! You'd probably like the Saxworks, which is basically a very good Dukoff, but I am sold out of the few I had. Have you looked into a closer version of the DV such as a 7? Or find a cheap Dukoff M or D and send it to a refacer. A Jumbo Java, say A45, is worth trying. Ditto a Meyer small chamber or Runyon Custom or Custom Jazz in about an 8 facing. Mojo can make these very responsive.
Is your Morgan an 8M or 8E? You might try the E.
In general, clean staccato response gets more difficult on very open pieces, say much above .085" for alto.
