Mike - I had a HBDX-48 up for 5 years at my old QTH with a Mosley
pro-67 (24 foot boom) and an 8 element hy-gain 2 mtr beam (about
8 ft boom) with no problems at all. Your system will be a little
bigger than that though.
I think that as a matter of general principle, when stacking antennas
the bigger/heavier/larger windload one should be at the bottom of the
stack rather than the top, to reduce stress on the mast. Perhaps
others on the reflector would be more qualified than I am to comment
on this one though. I would definitely add a thrust bearing if you
don't already have one. I did on mine.
