99 fletching, if you make yew longs from 70 does not cost anything.You will end up making money if you buy yew logs and bow strings in the G.E. and make yew longbows. They will sell automatically and will give you a profit of up to 30k(30000) gp per 1000 bows made. In retrospect you should make up for the costs of the previous bows you used to get 70. Unless you have 90+ woodcutting(power magic log cutting) maigc longs are only 33 more xp per full bow made. And unless you are moneybags you would lose so much money if would be unberable. Plus they do not sell in the G.E. so well.Lucky Fletchng!!!
