Well our big Outwell one is 5000hh.. but the camping madman who we saw reckoned that a tent to withstand wind was a big factor, as we found out in Angelsey, the wind was howling and I ain't joking, tents were getting flattened, broken poles but ours just stood it was really impressed but it was dear....
Making sure you have guy ropes out helps loads too! 
It has so many guy ropes it is untrue, plus metal poles... denise didn't sleep for three nights the winds were that strong :-?
I did though, which annoyed her even more 
Always found the worse the weather the better id sleep.
Any recommendations on alightly bigger but similar style as per your link.....looking too take the wife/twins away for some long weekends. 
But, is that alcohol related...........

Funnily enough....yeah was when i was doing the bike rallies.
One event seriously worse for wear and ended up cutting a slit in side of tent and hanging head out.....woke up in a very cold pile of (it wasnt porridge lets say) much too the amusemnet of a large group of people watching.
Dont think the estate is big enough too fit Loo-knees"s tent in.
The wife did ask could we buy a caravan instead of a tent....two slight problems with that,1st i wouldnt be confident towing and second im skint (ish).
So looks like a modest tent will have too do.
