Wandering Dasy, I don't think my wife would appreciate to sleep under the vestibule with her feet sticking out. Both of us would like to have a chance of a good night sleep. Using the Moment would guarantee that at least one of us doesn't have a chance. Most likely both.

Looking at the dimension of other two person tents (e.g. Big Agnes Fly Creek / Copper Spur, TT Rainbow / Scrap 2) they don't any smaller than the Hogback especially with rain flies.

I did set up the Hogback several times in the basement with dumbbells for cleaning and drying. So I know it's possible. Luckily there should be enough large rocks so that I don't have to carry the dumbbells.

This doesn't make sense to me. You're not proposing something asides putting the rocks on top of the guylines or wrapping the guylines around rocks? Maybe it's just that I don't know the terminology of PitchLock and TripTease.
