Haven't tried those.
I use the
Marauder stands that someone here suggested. I like them.
Similar concept of interlocking bases if you want to arrange troops. I just use them for displaying regular figures to ensure they stay standing for years without toppling (I also write the UPC number on a sticker on the bottom in case I want to cross-reference my database to know where a specific figure comes from).
The sad reality is that every single TVC figure has a different depth figure peg hole, and they're generally very shallow. I generally need to use a Dremel motor tool to customize each peg to its figure.
I'd be interested in understanding if these work any better or if its a similar challenge where you've got to tweak the peg to match the foot.
The older figure lines were much better at having standard sized foot peg holes. TVC is a hot mess.
