You can ignore the Outlaw.  What does he know about Osage, anyway...oh, wait.  Personally, I think you should be ashamed--messing up all that cedar kindling for a little Osage! 
All kidding aside, if you have time to wait to split it, the DVD "Rattlestick" has what I believe to be some good hints on where to split.  
As I remember, Outlaw, doesn't your "Monster" thread have some how-to on splitting?  Maybe I am remembering that wrong.
