EMT930 record weight

Hi all!

I'd like to try some record weight on my EMT930. I feel that
a better coupling to the plate should be beneficial. What record weights have those of you who have the deck tried?
I guess 0.5kg should be max not to overload the bearing? Also I'd like to use the break, so the spindle hole should let the spindle rotate when breaking. Any experience?

One candidate is Thorens stabilizer, other one of the TTWeight, and perhaps also Shindo bronze one.
