I have 2 B.A. sil-nylon footprints for the older model (approx 2010-2012) of this awesome tent.  They have both been gently used, but have no tears or holes and are still in good shape.  As the FC UL2 has been upgraded, these can no longer be purchased anywhere new but are free to anyone who will cover the cost of shipping + $5 for packaging.  Feel free to secure one, or both if you can use them.  I just hate to see them go un-used if someone has a need.  PM me if you are interested.
