I looked at both the BA SL1 and SL2 and selected the SL2 for that reason. Mind you, the floor area in the SL2 is still not excessively large at 27 sq. ft but it is quite adequate for 1 person. These tents have multiple tie downs in case of inclement weather but for normal use, several can go unused.

I also agree with BobG and the one shortcoming I have with the tent is remembering the drip line.
