Phantom's out--too heavy for the springs. Michell will make an acrylic armboard for it instead of the typical aluminum but the combined weight of arm plus board, if memory serves, cannot exceed 1 kg and the Phantom alone weights that.
For years I used a Graham 2.2 with a Shelter 901 on an Orbe SE and liked it a lot, so I think it'd work well on a Gyro, too.
