Woodsong Garrard 301, Artisan Fidelity 301, Shindo 301, SME 301, or etc.?

Chris at Woodsong does a complete rebuild including new platter.
In addition to highly developed plinths. Mine was $11K. Artisan Fidelity seems to go to a higher, but not necessarily better, level.
They are a few thousand more but Chris says that they farm out much accounting for the extra cost. Chris does everything himself and does an excellent job. I am thrilled with mine. Upgraded to a Triplanar arm and Lyra Atlas SL cart and Atma-Sphere MP-1 pre phono stage. Think his 301s are probably more like classic ones.
The SMEs are a new version and may also be more classic. No, only a SME arm. Think a 309. Maybe you can get a IV or V. But think they come only with the 309.
Do you have a 301? Rebuilt?

Chris Harban advised me not to switch to a much heavier platter.
That the 301 motor was not designed to move that much weight.
Although it does seem like a heavier platter would add thrust and a stronger tone. And the available heavy copper or brass platters are $1-2K. Does anyone have experience changing from a lighter to heavier platter?

A huge upgrade to my TT rig was putting it on a SRA VR platform. As always, never imagined there could be better SQ but I just changed from the entry level VR to the mid line Ohio Class.
Wow, what a difference! Why Ohio Class? Because SRA makes vibration control for nuclear submarines. Much more $ than a heavy platter but waaay worth it.

Heavy stuff on a 301 are a main issue.
Starting with a heavy platter. I will stay with Woodsong’s version of an appropriate platter. Not the original but not very heavy either. Think it is about 6 lbs. 
Think the slate and iron plinths are questionable. Woodsong’s plinth is a very carefully layered ply and panzerholtz affair. Not very heavy but appropriate for the rebuilt 301.
Then it is a question whether or not to use a platter weight.
I use a 2 lb Stillpoints weight and don’t notice any change.
Anyone getting good effects with a weight?
