Right the Omega Z5 is their generic line of Omega's. They have other Omega's with better sights, and stocks, but the Omega Z I am sure would be a good shooter. The Black Diamond on the other hand should be a real good shooter as well. I load 100 grains of Triple Se7en 2f and a 250 grain Shockwave. Also whether the BD you would purchase would be the same, mine will shoot conicals as well. It actually shoots about anything you want to put down it..
