Okay, finally got a chance to try out the heavy duty backdrop support and 2m x 6m double sided vinyl backdrop purchased fromXLStudiolighting via ebay.

This is a very sturdy, and quite weighty, piece of kit and will apparently support up to 15kg in eight. The 2x6m vinyl roll is specced at 7.75kg so no problem there. The stand is specced at 3m in height though if hanging anything more than a cloth from it I'd want sandbags on the bottom at that height.
The centre support comes in three sections. You can screw the two end sections together to support a 2m backdrop or add in a middle section to allow use of a 2.7m backdrop.

Now started the problems
The aluminium core that the vinyl is provided on is a fair bit longer than the vinyl itself which, unfortunately, means that if space means you can only use the two ends of the support stand you can't actually put the support onto the uprights as the core impinges over the support ends.

You can also see, in the above pic, the texture of the vinyl. It has a very slight raised square texture to it.
So, with much swearing, out with the hacksaw to get the roll to be able to go on the 2.2 metre centre support. (In theory I could have unscrewed the two support pieces from each other some but having a weak spot in the middle sort of negates the idea of a heavy duty stand if you ask me)

20 minutes later with 10mm hacked off each end, I was able to get it onto the supports.
As you can probably see, and I will attest, this stuff is very thin. I don't have a micrometer but I doubt it would be anywhere near 2mm, more like 1 and a bit.
As we quickly found, if you are using this on a carpet, even a relatively short pile one like the one on this room, you are going to get wrinkles, folds and shadows.

Putting weights on the corners may help, though I'm not so sure it would on carpet.
Switched round to black and it's, to my mind, a little reflective. I have been using one of those 'non woven material' sheets and that absorbed more light than this stuff. Obviously, the further your subject can get away from the backdrop the better and we're a bit tight on space but this is definitely a bit worse than the plastic/material hybrid.

Will be experimenting a bit more later and will post any further thoughts I may have.
