Lots of good advice there. I too was considering a new tent purchase and looked at Naturehike, I facied the copy of the Tarptent Rainbow 1, the Targa. I nearly bought it but then decided to go off on another way of camping, bivi and tarp.
I have a 'lightweight' Osprey 48L (I know there are a number of lighter rucksacks out there), a down sleeping quilt, a Thermarest Neo Air and can use either a Zephyros 1 (for winter) and a Marmot Pulsa 1 (for summer) so added together the weight is more than OK for me. Of course with other stuff and clothing and water the weight rises but I'm happy with my lot. I don't cook en route (I go to pubs, etc) so thats another weight saving for me.
The way I look at it, like so many others, why spend out loads of money on one very lightweight item when you can spread the lighter weight via a number of items. I would have considered a more expensive tent but I made the decision that I don't do enough camping to warrent such an outlay, I'd rather spend it on beer and good living!
