I have the older non-lite version as well as this. The original is getting on for 10 years old and has suffered a fair bit of abuse and is currently in at SMG for a bit of TLC. It's a very good tent, pole sleeves are wide enough to double pole it, ski loops on the pole ends to anchor it in snow and meaty guy lines. It weighed in at about 3kg and I trust it in all weathers.
The lite cuts many corners, all the fabric is wafer thin, the poles are DAC featherlite 7.5mm, guylines are single 1.5mm dyneema, pole sleeves are minimal, i.e. only fit one pole, the pegs are those 2g toothpicks. It comes with secondary guy points which I've used with 3mm dyneema in that photo above (you can just make out the glowing line locs) and swapped out the pegs for something more substantial which brings mine in at just under 2kg. I tried my old 8.5mm poles on it and they fit, just, but Vango assure me the 7.5mm are as good as the original 8.5mm.
It stuffs into a pocket on the rucksack with the poles and pegs slipped inside. It's massive for the weight and I found I used it more this winter than the Scarp as I like the space and it stood up fine, although not really tested.
The issues you refer to have, as far as I'm aware, all been addressed from the 2014 model onwards. Mine is from that vintage and has the mods.
