Alright, so I decided for the Malativas.
* Union Contact Pro: Toe ratchet gets stuck easily. Toe straps looked rather primitive.
* Raiden Phantom: Significantly heavier than the others, straps and ratchets only average, footbed poor.
* Flux DS30: Would have been my second favorite (nice ratchets, straps), but...
* The Malavitas had even stronger, and perfectly flying ratchets. Also the EVA footbed has better cushioning, they have Re:Flex and overall they appeared to be built more solidly.
So thanks everybody!
I personally liked the ratchets and straps on Raidens better than the ones on the Vitas. And the Phantoms have the airbags which are great for dampening but I've heard the Vitas are more comfy in everyday riding.
But the ratchets were like butter. So smooth.
