Opps, not quite today, but a week ago Saturday we were in Snow and Rock getting some essential skiing gear, and noticed they had a Hilldeberg Rajd shelter going for half price (and it was a competitive £260 when full price. Just a shame it didn't qualify for our 10% discount too!) so we're now just looking for an opportunity to use it
That is, once we've ensured we can successfully improvise some poles.
I reckon you could improvise support at one end using a bicycle. If you run a cord out from the tent/shelter over the bike (and preferably secured to it for extra rigidity), and then down and pegged into the ground.
I'd make the cord long enough that if the bike fell over, it wouldn't puncture the tent, and you'd probably need a good strong tent peg, but if you had one other support (like a tree or fence) this could work.
You could probably support it solely using two bicycle, but I'm assuming that you may be on the Tandem, in which case that wouldn't be an option.
As regards the Laser Photon, it's not only a very lightweight tent, it's also very compact, which is as much the reason that I use it for cycle camping. Compared to the weight of you and the bike, the camping luggage isn't all that heavier than my "normal" cycling luggage.
Laser Photons, and the variations on this theme (Laser Ultra, Laser Competition etc) seem to have been pretty common on several of the YACF camping events that I've been on. The one issue I have with mine, is that there is a reasonably large mesh panel, that can't be covered, so I wouldn't want to use it in very cold weather, since it would let too much of the heat you'd expect to build up, escape. Aside from that, I do OK with it. It's not exactly spacious, and it's not ideal for sitting inside of, but I find most tents difficult to sit in, and not hit my head on the roof, so that's not a biggee!
I'll use my Ultra Quasar when I'm camping out the back of the car, but it's quite a bit heavier than the Laser Photon, and a lot bulkier, so pretty much has to be strapped on top of the rack, whereas the Laser will fit inside a pannier, including it's poles, and still leave room for other stuff. The Quasar would fill an entire pannier, and I'd still need to strap the poles somewhere else.
