I think I have Pignut (also called Smoothbark) Hickory as per my Audobon Tree Guide. Running some 8" to 12" rounds through my Ryobi splitter and having to pull the dang stringy splits apart sucks. These are my first hickory logs and I hadn't heard folks complain about it. Wondering if I have something else than hickory...? The leaf matches super close in my field guide though.
