Lightweight tent recommendations?

lol that vid is ridiculous. I'm generally against tarps - just too compromised for our UK climate imho.

ives, where/when do you plan on touring so we can narrow it down further? eg., Scotland, even in summer can expect all 4seasons in a day! is it just for bike touring or hill walking? do you plan on using it a lot? the gelert is cheap for a reason(s)! That TN bivi looks ace but for that kinda money, look at laser comp. brilliant tent.

anyway, enough from me, don't wannabe the resident tent geek ;)
oh... to all those who pm'ed me re: atko. seller is looking to offload locally 1st (Manchester) - l'll repost here if its still available.

probably a couple of week long cycle trips : one in June and one in July/August.Staying on campsites, more than likely.
Almost certainly both will be in southern England.
