well, a few methods are slow, but somewhat break even or are profitable. Everyone knows about cannonballs, don't know how you feel about them. They are slooooooow xp but profit. Iron knives are another profit maker, yet another really slow xp. Making addy bars via superheating is breaking even, if not profiting a little bit. if you use a furnace it cuts the xp a lot but you profit about 300gp per bar. I believe you can make any bar for relatively no loss, but most have to be made at a furnace for that. Hope it helps. Just FYI, if money were no problem, make the highest platebody you can for the fastest xp.
