Donna, most shelters are a compromise in some way or another, and the MLD SoloMid is no exception.
I have one in cuben, which weighs in at 296g, and the compromises of the size are easily outweighed by the joy of carrying such a great shelter that weighs so little.
I recently spent a few days in stormy conditions above the tree line, and yes, rain entered the door when I was entering and exiting the shelter, but nothing unmanageable, even in storms.
I found the space allownce just right for the minimal amount of gear I was carrying. I am five foot nine and for five days my total pack weight comes in at about 6kg.
I am a no cook convert, and wouln't cook in the SoloMid, even with the door open on a nice day. I did this once, and the fumes were very strong.
When I want solo luxury, or hike with someone, my Golite Shangri-la 3 is much more comfortable, but at double the weight.
Mids are great, but in cuben, they are a real investment. I would suggest you look at what areas you are willing to accept compromise Donna, and what areas suit your conditions and intended use carefully. There is no one do it all shelter.
I hope this helps, and good luck with your choice, there is some great info here.
