ash does not have a very strong longututal grain . like cherry,, what I mean by that is that they will not follow the grain as osage, osage has a very strong grain and is very perdiciable, I have split many ash and cherry and sometimes cedar and they will split cross grain, I have seen this in some hickory before,but it is rare,, that is why osage is my favorite wood to split,because it has a very strong grain..
