The only Hickories I have used is shag bark or pignut but I think just about any of the hickories will work for you, look for strait even bark , hickorie takes a fair amount of time to season good but can be ruffed down and brought in 50 % rh for a couple months to get a bow , I like hickorie for a self bow or sinew back bows, I think hickorie gets a bad wrap somtimes because of improperly dried wood, I have 10 staves hanging in my shop that where cut 3 years ago that are taking some real nice natural reflex good luck with your build !
