I HAVE HAD good luck using wire rope clips/crosby clips
on the new style philly in beam truss applications (not as guy wires)
use 3-4 clips per end....have aLSO used aluminium nico press
clamps on philly beam trussess with no probs (not on guys tho 
only use the genuine grips on guy applications)..........
