>>5922471I only have Giorno with both Gold Experience and Gold Experience Requiem posed together using the just one side of a base with 3 holes and even then it feels tricky. The only other multi-figure display I have was using a Di:stage with has a lot of holes that SAS arms can easily fit into and gives better flexibility for more figures.
If you're keen on using Medicos bases then keep an eye out for WF packs on Mandarake that have 3 hole bases or AmiAmi for Di:stages.
Hopefully the anon that posted that pic could explain more into detail on how he made that possible.
