Omega should be fine. Pitch at .43 (that's actually pretty low as .75 is standard) and raise by 1 degree per day once fermentation starts. Once you hit 66* your beer should actually be finished at 1.010. The key is that you have to pitch correctly (don't assume you have have the 200 billion cells they tell you.) If you are brewing today it is probably too late, but I would advise making a starter, crashing it, and assuming 4 billion cells/ml of crashed yeast. If you are assuming on the yeast you may want to pitch as high as 1.00 just to be sure, save 5-10% of your yeast and crash it to figure out how much you really pitched. A lot of people say Conan gets more powerful after a few generations, and every time you make a starter it basically adds another generation, so if you had a week you might have enough time to make a 3-step starter and crash it.
