I know 15lbs for a lance is heavy, however steel of that weight and size would be at least 50lbs, since it's more like a supersized greatsword. I have weights that go well past 15lbs, it's really really not that heavy if you're used to swinging it around. Also much of Hyperion's weight is at the very base of the blade, making it easier to position, as opposed to it being at the very end.
So far it seems like Pollen wants to come to conclusions in the middle of both arguments. Iolanthe's spear breaches Sigurd's guard, warming up his buttcrack a bit, but at the same time his sword's tip will leave a slice in her bracer. I won't write it being a fracture, or a very large wound either, because she's pushing his arm slightly, and pressuring it away, that'll at least count for something.
Wait a moment, and I'll edit in a small cut. I'll be busy the rest of the day and all of Saturday, however...
