why wouldn't they work with the sub? they are all designed for oils, with the sublimator you need a piece that's more designed for flowers, asides from the fact most of them are male joints requiring a frustrating male to female gong, the bases are all too small to handle the sublimator without tipping over, the chambers are also too small for those fat sublimator rips, you could only do mini rips.
the closest piece atm is the stereo matrix knock off, but i already have a legit stereomatrix so eh ;/.
the fc matrix ion v2 looks alright but once again it's a fairly small chamber dude. maybe it's personal preference but i need something at least the size of the matrix clear with the sublimator.
that's the frustrating thing with dhgate vendors, look at all their larger pieces, they are so overpriced for how basic they are.. they have this logic that the more glass involved means the more expensive the piece should be, this is great for oil lovers because they are producing oil rigs super cheap but i'm not seeing anything decent come out from china for flowers.
What about the YQ-42? It's a solid piece, pretty freaking heavy, and you could choose if you want more or less diffusion based on how you fill it. I bought one for a combusting friend - was really impressed with it
