Thanks for your interest! If you're asking which version I'd recommend for Omaha hi/lo MTTs, I would not recommend any of the NoteCaddy Edge packages. None of them were designed specifically with this format in mind, so honestly you probably won't get a lot of value from any of the packages. If you wanted to try one out though, MTT version would be your best bet I think.
If you're asking which version(s) to get for MTT, and Omaha, and Omaha hi/lo.. I would say to get the MTT package for MTTs, PLO package for PLO Cash, and no package for PLO hi/lo.
