I guess u didn't tried trekking yet,otherwise u'll need a porter just to carry ur tent..
@ALL
while trekking one think u must consider is the time period required to install the tent.So u need a light weight tent which could be installed in 5-10 mins.B'coz after walking for like 7-8 hours in mountains and breathing air as light as feather carrying 15-20kg weight all day long,and U r dead tired,ur patience only last for 5-10 mins after that if the tent is not installed u either burn it or put it aside,open u sleeping bag and go to sleep..
