VPI Classic 1 isolation upgrade

Hi! I would like to upgrade the isolation of my VPI Classic. I have the following right now:The TT is resting on the top of my custom made rack. The top plate is a 2" MDF what is on "Herbies fat dots" dividing between the lower part of the rack for the phono. There is about 5" sand on that plate.On the sand, I sandwiched an inflated tube between a tile and an 1" MDF. The sandwiched layers are not touching the side of the rack, just the sand, and I used a straw to cancel the vacuum.

I was thinking about the following:
1. Symposium VPI legs + Rollerblock jr s under directly
2. Terrastone VPI legs + Terrastone rollerbearing under
3. Symposium VPI legs + Symposium Segue ISO
4. Change the upper MDF plate to marble, leave the mdf or the tile on the sand + any of the firts two options
Which one would you choose? I dont really see the need of the Segue , I think I could rather improve the lateral isolation with roller bearing.

Thank you! I used the last few months to find out which way to go...Money is an issue, so I would do it around for the same sum as any of my 4 choiches.

What is for sure. I am going to change the tile and the 1" MDF to marble. Does it make sense?
What would you use if not a bicycle inner tube in between the marble slabs for x axis isolation?4 Townshend Audio Seismic Pods? Something a bit cheaper? Or is the inner tube just as good as any other in a setting like this? There is sand under. 

For the y axis isolation, under the  VPI Classic feet, which roller bearing isolation would you use?

Yes, it`s pretty difficult. They say, there is some difference between the norwegian birch and the baltic. Can it be sufficient?

Shun Mook concept. 50% of the internet are raving about the sound, 50% think that`s just a hoax. I think the truth is something in between. For me, it`s convining enough to pay for the legs. Let`s see what`s coming after.

Thank you for saving me from the marble...Meanwhile I am looking for baltic birch plywood what is kinda difficult here in Norway. Do you know any other type of wood what can be just as good?
I am gonna stay with the inner tire in between the layers, or use "Herbies" sheets. I got plenty leftover. The whole thing is in a sandbox. I don`t feel like using my money on Townshend Pods, but on something else...

I checked the Ingress Engineering products and I would definitely go with their roller bearings and one of the feet upgrade mentioned earlier.
But.
My future plan is to upgrading system with Shun Mook resonators, so it would make sense to save up for 4 Shun Mook Diamond Resonators under the VPI TT.. Have you ever tried that?
