Hi SF,
I am using HyperMill v9.7 with 3D & 5 axis licenses, I am also using HyperCad 2008.1
with reference to your spiral dilemma, if you have the cycles of course, have you tried "3D Equidistant Finishing", this is a versatile cycle that can be used for many applications, it is also easy to use with not much work to create your spiral in to dead center from outside the billet :-
or indeed inside to out stopping at the edge or pocket wall etc :-

,
the cutter used here was a Ø20mm endmill and I have complete control over the step over, combining this with a 2D pocket cycle to spiral down in the center I could then spiral out taking whatever stepover was needed.
I also do not seem to have the same problem you have of identifying the highlighted cycle.
Hope I haven't missed the point !
