1 and 1/2's are a great training method. But, seeing as how this is the "beginners" section, I don't think that Flip needs to be worrying about things like 1 and 1/2's at this point.
Just pick one and try to build up your poundages on it as much as you can. Combine that with a caloric surplus and sufficient rest and you'll see results. When you plateau on which ever variation you choose, switch to the other one and repeat the process. Then switch to maybe dumbbells, or arnold presses, or BTN's, etc... and so on and so on.
Continue to follow this pattern consistently for years and you'll see noticeable and significant results. There really are no "secret" or "magical" training methods or exercises that lead to success. Don't make this more complicated and harder on yourself than it needs to be.
