That was something I did after the freestanding inner. Since I had the poles holding the inner up I put the fly on top of that.
Many reasons really. One was to give it a different look and , in theory, more wind resistance and better snow loading.
The wind resistance is provably correct however it does need some fiddling to keep the poles in place under snow loads (tested with wet blankets...) so not really worth bothering for me.
Anyway, now I prefer the look of the re-designed Scarp to my mod , so that is the way I will go eventually.
