You can't compare a Bibler tent to a Kelty tent; 
it's like comparing a Porsche to a Yugo. If your 
going to buy a double wall tent, go with a company 
that has proven themselves in the mountains (ie. 
North Face,Bibler,Mountain Hardware). One company 
that makes a great proven tent, is Wild Country. 
The "Mountain" tent is a 2 person tent,has a large 
vestibule on both ends and has similar weights to 
most other 2 person double wall tents. Think about 
weather or not you want to potentially hang your 
ass out on the line, with a Kelty.
