I used a Seedhouse Sl2 for a week and while it was roomy enough (I'm 6' as well) I had real issues with the design. The rainfly hangs over the tent in such a way that opening it after a dewy morning dumped water into the tent and on my sleeping bag. During rain it would be even worse, since there was no overhang to keep rain out of the tent when getting in and out. I ended up exchanging it for an REI Quarterdome. Not only does it provide excellent headroom, but I can toss bags under one side, and get in and out on the other. More importantly, the rainfly actually works to keep the rain out.
