Omaha, stud, & little green book feedback wanted

[beekeeper]

I did try to search on this, so sorry if I'm rehashing old news. I'm looking for a good book on <font color="blue"> Omaha Hi Lo</font> , and would welcome any recommendations.

If you've read any of these can you let me know which, if any, are good? Thanks.
