Best bang for the buck is Kelty Gunison 3 man tent on sale at there web sight. Weight is just under 8 lbs but if you split between two people you will have a very good tent for the weather. Check out there price on sale very good deal.
I'm 6'2 and my Brother is 6' 4 I have used the Kelty Gunison 4 man for back pack hunts for both 2 people and three in it and it worked but is weights just under 10lb which split 2 or three ways to carry makes a nice tent. I have had it in the snow and temps to 9F in Colorado above 9000 ft. and while not a true light weight tent it stands up to wind and rain and snow very well.
With three hunters we used a 4x8 tarp to throw our packs under at night with two Hunters we just put them inside with us.
If I was backpacking alone I would buy a Copper spur 2 UL man tent or REI 2 man half dome.
