Orbe SE with Graham Phantom or Brinkmann 10.5

If there are any members with direct experience of these combinations, your experiences/thoughts on the match-ups would be greatly appreciated.
I believe the Phantom is a bit heavy for the Orbe. As I recall, arm plus armboard shouldn't exceed 1 kg for proper spring function. The Phantom is that by itself. FWIW, I ran a 2.2 with and Orbe SE for years and thought it a really nice match.
I heard directly from Artech that the Phantom was too heavy. The consensus seems to be that the synergistic "fit" is the SME V; but I never went there when I had mine.
I owned the Orbe SE with an SME V and I can attest to the fact that it is an excellent combo.
