Have you picked your arms yet?
This Acos Lustre GST-801 is my rear 9" arm, extremely rare to find it in Mint Condition
I learned about it here, actually someone, wish I could remember whom, found it for me, I'm so thankful.
Unique Magnetic Forces used for tracking and anti-skateEasiest/smoothest VTA on the fly I have seen, removable headshell. If one has removable headshell, the other, presumably your long arm, can be fixed cartridge.
I like that arm so much, I almost buy it every day.
