So I had a thought, and so as not to start a completely new thread, I'm bringing this one back up.
I'd like to at least try Feruchemy over Allomancy, and this is why:
Most skills require something saved up in order to use it later. Alright, all of them. But weight can really be played with both ways. We know in Sazed's fight with Marsh that when he increased his weight, it threw Marsh instead. But he also could avoid damage from getting hit by decreasing his weight. Sure any blow would throw him, but his lack of weight would keep bones from breaking, and the wind resistance would slow him down before he went too far. Plus, with normal muscles he'd be capable of impressive acrobatics, though he'd have problems on a windy day, and a coin shot at him would be problematic unless he could get out of the way before hitting something... And he could move much faster with a little less weight. Throw punches with high speed and increasing weight before they hit to increase impact. That would save on Pewter.
All that would take a ton of practice, and he'd have to probably get the metals pierced into him or swallowed (or use the ones already buried inside his stomach), but Sazed could be deadly. Especially if he saved up on gold, steel, zinc, tin, and pewter.
I wonder if bronze has a use beyond comfort and survival in extreme temperatures.
