ya that might be a little long
i also agree with Danam on the backing of a board bow.
i have made a couple of hick board bows,72" ttt,backed them with cotton camo cloth with tbIII glue,look and shoot fabulous
a longer bow is more forgiving and accurate than a shorter bow especialy for newbies in trad archery
yes piking them(cutting each limb shorter) will increase weight but you will need to retiller it for the shorter length also
god luck and post pics,lots and lots of pics, strung ,unstrung,side profile,front profile,,full draw,pics of the handle and tips etc
we like pics,plus it helps everyone gve the best possible advise,and trust me the guys on here are good real good.
they are some of the best wood bowyers in the world right here.not to mention they all are more than wiling to help you make a good shooting bow.
peace,
