Ian, i was going to say that with a pulk, it's really no weight at all. My stove set weighs packed, a little over 3 lbs, and since it's collapsible, not a lot of volume either.
Considering what you're getting for 3 lbs, and if it's on a pulk to begin with, really not much weight at all. Lot's of people still use packs that weigh 4 to 7lbs on average, now if you have a 2 lb or so pack, and a 3 lb stove, you're still ahead of the game compared to a lot of folks.
I didn't get this for backpacking so much though. I wasn't on BPL when i purchased it, and didn't have much a clue about UL, SUL, etc, but even then i realized yeah, it's more weight than i need to carry for most trips.
However, a little while after i bought it, i was excited to try it out in the field, and made the big mistake of bringing it on a late spring/early summer week hike in the White Mountains of NH. I was out of shape, carrying this and too much weight in general, and yeah those little mountains (but lots of constant elevation gain/loss) kicked my butt, and kicked it hard.
Found my way over here after that experience (when the student is ready, the teachers appears and all that). What i did primarily purchase it for was in case we had to live in the woods for an extended period of time. If that does happen, i suspect it will be about one of the smartest purchases i've ever made.
But, if we get enough snow here this winter, do want to try it ala pulk style. Thinking about making my own out of UHMWPE plastic.
