a tent that relies on guylines alone would be my idea of a nightmare. the weight savings is attractive, but IMHO there is a certain level of hassle that justifies carrying a certain amount of weight. that's just me, though. at the end of a long day hiking i have no desire at all to spend time figuring out where i could tie off my lines to create a workable shelter. sometimes it takes long enough just to find an acceptably flat and empty spot! plus i'm lazy, which is why i've moved away from tarps and on to tipi-style tents.
sorry, no opinion on the stove. i love to sew gear (or do i hate to love sewing gear?), but stove-making holds zero interest for me.
