I put a pulley on the tram line and run the line to the top of the mast.
Backguying the mast, of course. 
 
I run a halyard line to a pulley at the top of the mast and down to the
ground.  

I make up a rope harness that extends out approximately equidistant from the
boom center of gravity(cg).  I make a slip knot in the harness at the CG to
make an attachment loop.  I connect it to the pulley and attach the halyard
line to it.  

I usually have two tag lines on the boom far enough out for ground crew to
easily control from the ground, but close enough to the boom-mast plate to
reach to release once the beam is attached to the mast.  

Seems to work fine for TH6, A3 and C3E and 70' tower.
