I've got some hard maple that is 11/32 and 32 inches long that wieghs in around 675 grains. I have some of the hickory heartwood that I haven't cut the square ends off of yet. When I get them a little further along I'll see how they compare to the hard maple. Hopefully I will be able the cut the hard maple to length and cut the nocks in tomorrow then see what they weigh at 29 inches. I have a dozen of the hard maple all slicked up and straightened already.
