In reply to LauraJ:
What do you mean by a porch with mesh? The majority of tents have a mesh option for the door to the inner but I don't recall seeing one with a mesh flysheet. Wouldn't midges just fly under the edges, or am I misunderstanding?
On those really bad midge evenings/mornings camping in Scotland, I have just retreated to the inner with brief forays to the porch to make a brew.
