I want to upgrade my Turntable to something heavier

Congrats! Great table and great cartridge! I was running ML on my VPI Prime X for several months and loved it. Upgraded to Umami Blue. If the ML is new, it starts improving after 30hrs of play time and peaks at close 100hrs. Be patient with it. 

Why don't you just put some lead weights on the table you already have?

While in Koeln, there was a Transrotor dealer in town. These must have been the heaviest turntables I’d ever seen. The German engineering on these tables is mental.

I don't get why you need a heavier TT other than the obvious, For the dogs

But I get it if you are retiring soon

I made the Jump to VPI and not regretting it. choose wisely. Dr Feickert tables are great and Lastly Clear audio. I would stay away from Rega simply because it uses the principle of lightweight but rigid. I owned a fully modded P6 (new with all the bangs and whistles) and when i got the VPI super Prime, for me, the sound it presented was at another level. another brand is Kuzma.

good luck

Oh, I missed the Post where the OP decided to get the Vpi Prime

Well, done. wont regret that specially you'll be getting the ML, (mine was the Blue)

suggest that you look into a Transformer and a very good Phono pre-amp

and seriously, you do not need to upgrade the TT. it has all you need.

just enjoy the music and make sure you install the Cart really well

Also, if you do not like to deal with the Uni pivot arm, there is a VPI product that fixes that problem

good luck
