Hrrmmm... I like SMT. It's cheap, easy, and performs well. I haven't tried the ceramic paper, but I've only tried single sided reflow, and it worked fine without. I'd also worry a bit about fumes during reflow so doing it under a vent or hood (they recommend no drafts?)

The challenge I saw was with silk screening the solder paste with the right alignment and thickness. Placement with tweezers and a binocular microscope (or young eyes) went fine once you do a couple. Post reflow rework substantially increased yield from ~80-90% to 99%.

Make sure you have a test for those parts before you put then all together wrong!
