I have fully figured out the heavy counterweight issues and now have many great fixes. The good chaps at Rega UK received my whining email that their heavy weight was a lightweight. It’s like 2 grams heavier than the standard. My Dynavector and Zu carts are heavy beasts! So they kindly custom machined me the only 150 gram tungsten Rega counterweight in existence!! You can now special order them if needed for $295.
