Oh, I should add that I found mine would slowly drip from the end of the vent seam in heavy rain, which lands in the middle of the porch area (not ideal if you've got a footprint).
Mine does that too. Unlike you, I've not got around to sealant yet (since 2008). I just put out a pan with a J-cloth in the bottom to catch the drips.
I reckon the inner could benefit from a second cover-able vent at the foot end to provide a bit of airflow when it's warm
Where are you thinking of? There's a low level vent at both ends, so as far as I can see, the only other useful place would be a second high level vent on the side opposite the door (where it would be inaccessible from inside the tent).
It's notably slower to dry in the sun than other tent fabrics, though this can be mitigated somewhat by (perhaps counter-intuitively) closing all the vents to allow the air inside to heat up
The other counterintuitive thing is that if you should be troubled by condensation on the inner, the correct course of action is to close the outer vents, thus allowing the air between inner and outer, and the inner, to warm up some.
What I particularly like about the Akto is how easy it is to pitch, more or less regardless of weather. The placement of the main pegs is all on guys, so stoney ground is generally OK.
The inner sizing is a bit more biased to porch space than other similar tents (Zephyros, Power Lizard etc), so there's no way you'll squeeze in a second person. On the other hand, there's room to bring in all 4 panniers and still leave the entrance fairly clear.
I had a Jetpacker once. As you say, like a coffin, not helped by remaining very low until half way up from the foot end. Getting trousers & socks on was a lie on the side job as there wasn't the knee room to do it on your back. The Akto is much better.
