Yeah, I've got the Spiro itch now too (isn't there an ointment for that?).
For the past couple of years, my playing has delineated itself into two distinct seasons; orchestral in the fall/winter/spring and jazz in the summer. With the dearth of jazz gigs in my area, the paths rarely cross (save for a summer pops concert or two), so the need for a "hybrid" string has become moot.
So, after my last symphony concert (Strauss's Don Juan no less) on May 7, on go a fresh set of Spiro Mittels. I'm going tip my toe in the h20 by starting with just the E and A and see how they sound with the Pirazzi D and G.
