I'm 2" taller than you and have successfully used two of the tarp tents you mention. The SMD design is tight though, and the lack of a fastener on the ID doorway requires some care to prevent water ingress in windy weather.
I currently use a Golite Hut 1 which is plenty long. They are getting hard to find though, and the shangri la 1 which replaced it is a lot shorter from what I can gather.
I also have a GG 'The One' which is just long enough for me, but I keep my WPB jacket over my feet to stop the footbox of my quilt catching condensation.
