Long-term LP12 spinner here.
Our LP12 has the KAROUSEL bearing, the STACK AUDIO sub-chassis, ultra-rigid BLACK DIAMOND RACING CONES threaded to the plinth for feet, pimped ORIGIN LIVE DC motor speed control unit powered by a massive 160W/24V ultra-low-noise LHY Linear Power Supply. We run the solid carbon BOSTON AUDIOMAT. The jointless, silicone BLUE BELT completes the ensemble.
I can report that our WAND PLUS 9.5 tonearm is an absolutely stunning match for the LP12.
I'd also mention that removing the (singing) LINN springs and installing AUDIOSILENTE silicone mushrooms in their place (~$100 in parts) was one of the biggest sonic upgrades our LP12 has ever undergone. I'm in touch with dozens of global "springless" converts and not a single one of them have ever reverted to the springs.
As a side benefit, due to the superior support and much restricted sub-chassis travel, I suspect the silicone mushrooms would allow for a far heavier arm to be happily fitted to the venerable old fruitbox.
