Good choice, Anto. I looked at the Scarp, and decided that a 3-season tent would work for me. I did get an additional "crossing pole" for the Moment. It goes head to foot, and converts the tent to free-standing. (It also adds a bit more strength & stability if you should have to deal with snow.)
I found the crossing pole valuable on my western trip, because a lot of time, I pitched the tent on ground that was baked hard and/or gravelly, and it was difficult to drive in a peg & have it hold well. (The Moment requires only two pegs, one at the head & one at the foot.) Usually not such an issue if I'm camping in Ontario -- there's a bit more topsoil here.
The extra pole adds about 6 oz. I got the cheaper alu one -- the carbon is lighter, but costs more. I've used it in the attached photo, though it's hard to see because you're not looking across the pole--it's in line with the long axis of the tent. (Also, the resolution in the photo is crappy -- I had to reduce it to post it.) I rigged the tarp because 20 minutes earlier it had been raining hard, and I wanted a dry spot to eat supper & breakfast. Of course, the moment I rigged it, the rain stopped for good and the sun came out. Mountain weather.
