Thanks everyone.
Perhaps I wasn't too clear when I asked the question, but we seem to have got there in the end...
Airmanship aside, (yes, I agree it's less than ideal, but it's LHS prerogative; yes I understand close-in turns and reflapping in the turn, do them twice a day, but generally at a nominated airspeed, not 'one click'; etc etc - I wasn't really looking for a pissing contest <img src="wink.gif" border="0"> ) all it seemed to achieve was synchronisation between FD pitch command and target airspeed on the ASIs, as you'd expect in other modes. What I wanted to know, down deep, is this: apart from making the picture look nice, does it achieve any real benefit; what about the engine failure mode, is command pitch still v2+15, presumably so, but what monsters lurk behind?
Thanks again

(D*mn: missed one!)
