A bit more info wouldn't hurt, what style bow you wanting to make? What draw length and poundage you shooting for? I would agree with the guys on trad gang it will probably need backed as there apear to be some violations
I tend to like wide limbs on most white wood like maybe 2" throughout most of the limb and I tend to make most of my bows around 62 to 68 long but really it all just depends what you want to do with it. I like blackhawks design he has been using lately with the wider limbs and the very narrow tips. Sorry not much help here but probably need more info for some of the more experianced guys to give better ideas on demensions. I would also go with a flat belly on this wood and again back it. I know Gordon has worked with this wood so maybe he will weigh in on this one too.
