I couldn't wait any longer, though my Hilleberg Nallo is almost the perfect tent for me it does have a couple of small flaws for my trip through Africa (any excuse to buy more gear).
I won't bore you with a review of my MSR Hubba Hubba, but here's my first impressions, its the first of January and I've already camped once, its going to be a good year!!
What was wrong with the other tent?
In warmer weather its just too warm, and the inner(outer) tent isn't self supporting. Not the end of the world, but a pain if you plan to cycle through Africa for 18 months.
First impressions of the MSR?
Plus: It's light, much more spacious than I expected.(bonus for Shane the claustrophobic), it has about the same if not more internal space as the Nallo, though is slightly less wide (of course because its a 2man tent!). Its easy to set up, and unlike some people claim it is possible to put up the outer tent first, though it is a fiddle to get the hooks engaged(could be because I have the newest version). Plenty of storage space. And most importantly and the main reason I bought it, its self supporting and the inner tent is made of mesh, so if you put only the inner tent up its nice and cool:).
Minus: The built quality is good but no way as robust as my Nallo but that is to be expected with a tent that is half the price.......I dont think I'll sleep as peacefully in a heavy storm though. The ground sheet is very thin, I dont think it would take much to start leaking (hope I'm wrong), but wont be seeing too much rain in Africa anyway. The tent pegs seam quite cheap, as are the guy line tensioners, I think I'll be robbing those from my Nallo :)
And last but not least its yellow! great for photo's but not so handy for stealth camping.....ahh well cant have everything.
Time will tell if I've made the right choice, trading in my trusty castle for the yellow thing......

Update: Msr have seen the light, the newest 2011 Hubba Hubba is green!!! >CLICK<
