The most effective method is to RuneScape gold use yew long bows as you mentioned. It's quick and easy, and it makes you a lot of money. Selling them is faster and yields more profits than alching. They can be sold, even if you want to make magic exp. Many people will advise you to use magic long bows to speed up the process, however it's so hard to find magical logs that the time-exp radio is definitely better than selling longs of yew.
You'll make more money by buying logs instead of the yew longers(u). You can make more money depending on what price you buy the yew shorts(u). However it takes longer due to the use of the string X option. This means that you'll earn twice as much from yew logs.
Do you think I should create the Maple Longbow(u), until I can create a yew longbow (u) and then sell those? Are you suggesting I should string the Yew longbow(u) and then sell them? Or should I just offer the Yew longbow(u).
If you dont want to miss the magical experience and u do care about time, listen to the advice cheezy offered you. I'm only 81 however, mainly due to the fact that I lost interest in the game for a couple of months. One of my buddies, ironically enough, became a member after I had already achieved 70 fletching and he beat me to lvl 99.
The idea was to make use of his decent runecrafting skills to buy essense, then create nature ranes in bulk (usually 1,000). Then, he would make his own yews, and pick the flax. Then the final step was to make his bowstrings and buy old school rs gold fly his own bows. He took the same route like I did.
