i don't think board bows are easyer per se, you still have to layout, tiller and exercise your bow, plus pic out a quality board, in mho it's an inexpensive way to get started and get something going while fresh staves are seasoning, you can use red oak of maple from lowes, but i would try to get some hickory or white oak, very good beginner woods, Bub
i just finished a hickory bow it's on the third page
