Applying this to the the Schick and Graham arms is not difficult. The Graham is out for me because it is a unipivot arm and they are inherently unstable. Graham uses a set of opposing magnets to stabilize the arm and it is most probably the best unipivot arm out there but it is extremely over priced. The Schick is too heavy, is not a neutral balance arm and it's vertical bearing is too high. Both arms have additional contacts. The Schick a removable head shell and the Graham a removable arm wand.
Arms that I really like are the Reed 2G, the Tri Planar and the Schroder CB and LT. I put the Schroder CB on my new Cosmos. Mark Dohmann designer of the Helix displays his turntables with the Schroder CB. Peter Ledermann of Soundsmith fame is big buddies with Frank Schroder who is designing an arm for Soundsmith.
