That makes me feel a lot better David. A bit of a thread developed on Twitter including a recommendation to add linelocs, which I can understand and will now explore. It is frustrating to be able to get it right sometimes and not others but it is clearly doable. I'm hoping Will Wood will do a step by step set up video as to how he does it. Other than that though it did do us brilliantly.
I realise I'm a bit late to this thread. David 14 are you also 'Fell Bound'?
I bought a 0.74oz Duplex earlier this year and took it on the Pennine Way in June for use by the two of us. The 0.74oz was really my wife's (perhaps understandable) desire to have fabric a little less transparent. I think it is a fantastic tent. I have found it fiddly to get a taught pitch and am not someone who struggles with pitching tents first time. However, when you see Joe's set up video and any of Will Wood's videos they have it drum tight so I know it is down to my ineptitude. If you don't get it drum tight it is not significant and even in strongish winds it just flaps a little rather than feeling like it will come down. There is clearly a definite 'knack' to pitching it right first time that I haven't yet got but am getting towards.
