There's no set answer to that one, at least the bow part. People have been arguing over this since the bow was invented. What kind of bows? Where will you be using them? Some of the better bow woods would be osage, yew, mulberry, hickory, ironwood, ipe, or any of a number of other ones. Some woods are better for some designs or climates. It's hard to beat osage as an all-around wood. But that's just my opinion. Part of the enjoyment of this obsession is experimenting with different woods and designs. As for arrows, that one's easy. Cane. Period.
