Don't forget though, some of the BD tents are only water resistant, not waterproof. I saw a review of a First Light on another site and the owner said it leaked constantly in hard rain with water soaking the walls and leaking as soon as you or your gear touched them.
(also from the poles. Franco)
Those are the one made with Epic (they are yellow)
Epic seams to work better when clean, however after prolonged heavy rain they do leak.
That does not apply to the "Todd Tex" Biblers . That version of PTFE is very water proof.
(once you have seam sealed them correctly...)
Some of the BD are now made with Nano Shield , (wasabe green...) this is supposed to be more waterproof than Epic.
