Thompson Center Omega

Does anyone know the difference between the Omega and the Omega Z5? How is your Omega holding up?

 

I am no expert but I really don't think there is any difference in the action, I really think the difference is in the options that are available in the Omega, The Z5 being the No-nonsense model. and more reasonably priced, I have been shooting black powder for several years, (I use a Knight) , I think the Omega is a great rifle, and although I like my Knight (who's ownership is in question) I think the next one will be the omega.
