just calculated a bit of smitting for myself... making mith platebodies from 70 till 85 would result in this : cost of buying 49378 bars : 53,278 k selling all the platebodies : 33,379 k total loss : 19,899,334 gp then 85-99 would result in ... cost of buying 118945 bars : 266,912 k selling the platebodies on ge : 232,418 k total loss : 34,494,050 gp so if you want to lose 54,393,384 gp for training to 99 starting from 70 ==> smitting if your skill to do! but !! ....crafting with ruby amulets would result in only 23,127,560 gp loss if you do 50 => 99. you choose, choose wisely ....
