Skill Bonanza: Urns, Ashes and Shortcuts

I think the urns are pretty good as long as you're training the skill and need to bank after every inventory (no dopisit boxes though). That way you can always carry 2 urns, fill your inventory with fish or smith an inventory, teleport any full urns, bank and start again with 2 urns. That way you're inventory is done slightly faster but you get experience in exchange.
Note I said 2 urns in your inventory, so the second one starts filling as soon as the first one is full.

As for the ashes, I sure hope they'll make prayer cheaper again
