one caveat: Silnylon canopied tents will pack up smaller than urethane coated nylon tents of similar design.
looking at the tents you mention, if one has a silnylon fly, the pack size should be smaller.
Compare the standard Black Diamond Betamid or Megamid with the Black Diamond Betalight or Megalight for an accurate depiction of weight and volume of silnylon vs. urethane coated tent canopies of identical construction.
Whatever tent you decide on, I strongly recommend packing a seperate silnylon tarp for picnic table awning, bike cover, privacy screen, windblock, supersize tent vestibule, etc.... 8x10 siltarp packs up the size of a small water bottle.
