Yea, dont start any yews until you are 70 fletch, i.e. yews longbow. I suggest you keep on cutting willow logs into longbows and sell to shop, dont be afraid that you will lose money, because you will earn way more $$ back after 70. From 70-80 (or 85, because you will lose money too by fletching magic shortbow), I suggest you buy yew logs 250-300, and bowstrings for 150 ea, and fletch them to yew longbows, and sell them back for 600 ea. That's some easy profit as 150 gp each. \
