I just got my 1.7 about ten days ago. I spent two nights in it on a 20 mile backpack trip last weekend--it was great.
I ordered mine with straps and I'm not sorry I did. Combined with two carabiners, set-up takes about 45 seconds.
The only thing that MIGHT make the system better would be to substitute the carabiners with Dutch clips.
Straps are great!
