Graham Phantom Supreme?

Here is something really useful, the adjustment tool from Graham for his Arms.

The new one for the supreme allows the height of the plastic flip guide to be adjusted according to cart height. This jig is a godsend especially for carts that have a short cantilever buried underneath the cart body like the Koetsu's, Allnic Puritas, ect.

The 10" arm for the Graham is the way to go. That was Musical Surrounding recommendation anyway.

Did they say why?

Dear Lewm, dear Rockitman, - I can't resist, but I now have to second Syntax' choice for the 9" arm wand. While I am certainly usually try to go for increased effective length, the 9" standard arm wand is the best for the Graham Phantom.
Why ?
I leave this to Syntax to explain - as it was on his selection of all 3 arm wands that it was discovered.

The longer arm having more mass also increases inertial mass of the cart which can be problematic depending on the cart used. Longer arm tubes also allow for more resonance. Bob Graham said this to Musical Surrounding and believes the 10" is better overall than the 12" even though you will have slightly lower tracking error with the 12". That's how I understand things anyway.

Dertonearm. the 10" arm is the sweet spot according to Graham. Lower tracking error than the 9", but less effective inertial mass than the 12" which can be good depending on the cart.
