Eventually, I have got the "Optimax" soft-top (or Supertop Sunrider, as it is written on the installations instructions).
It seems to me that the hardware is the same as for the Sunrider and the cloth is simillar to the Sailcloth. And it has tinted windows.
So it's a strange combination (and it has an odd colour, too - green on the exterior and beige at the interior, but that's the way I wanted it - it was cheaper, 500 Euros, and it matches my seats).
I just can't wait to get warmer, in order to install it.
