Large Hubstacks

Does anyone know what’s the largest (in diameter or width) hubstacks? I’m constantly using my turbofly/aquarius (synergy caps on Aquarius) for offstring and as you can imagine, it’s much more difficult to grab than say a stacked hayabusa.

I would think z stacks or t stacks but pretty sure those won’t work with synergy caps but I might be wrong

I thought so I wish synergy caps had different caps, but for my turbofly it takes z-stacks but even so they are very small. I actually just glued together the smaller z-stacks to my spare lateral caps and it was pretty decent!
