This thread is almost 2 years old. I've stopped using screw-on gas canisters they are more than twice as expensive as the old style pierceable canisters so I've gone retro back to using those and use a Camping Gaz stove. eBay bargain, old but brand new / unused. It's bad enough as it is having to spend too much in all these little ripoff shops scattered about in the Highlands on food without having to pay over a fiver for a piddly little gas bottle, get stuffed. The pierceable ones are usually £1.99. Found one shop in Fort William up the other end of the town selling them for £1.79 which was pretty good.
If there's not enough room for your stuff inside the tent / tent porch put what you don't need in the tent into your pack and put it outside the tent wrapped in a bin bag that's what I do if I'm using a one person tent. It's just a matter of getting organised.
My Zephyros has had it already, the eyelets on the webbing are worn/fraying due to it (the pole) being too taut, and the zip came off due to getting continually snagged, it got caught good and proper during my last trip, all I could do was pull it off, so now its no longer double zipped. I don't think that tent can be repaired, I'll have to bin it I think, not impressed with that tent at all. I'd get a Vango they're better quality. Not a Banshee though one of these:
