You can knock almost 1 kg off that weight with an F10 Helium. I've been quite happy with mine so far in terms of strength in quite strong wind, though it does tend to make quite a bit of noise when it flaps. This was in a strong wind in the Cairngorms...
On the broader front of weight reduction when solo overnighting, it's quite remarkable how you can cut down weight if you put your mind to it.
I used to use (for winter camping):-
Rucksack: 2.2kg
Tent: 2.6kg
Sleeping Bag: 1.6 kg
Mattress: 0.6kg
TOTAL: 7kg
I then decided this was silly, and moved to:-
Rucksack: 1.1kg
Tent: 1.35 kg
Sleeping Bag: 0.8kg
Mattress: 0.2 kg [3/4 length inflatable)
TOTAL: 3.45kg
And even lighter if I bivvy...
PS the one area where I really think it's worth sacrificing weight for comfort is tent size: the difference in weight between a typical 1 man tent and the same type as a 2 man is negligible, but the increase in comfort is huge. So I would recommend always getting a tent 1 man size bigger than you plan to use it for (eg 3 man tent for 2 people). My Helium is the 2 man version.
