It is not about "handling" heavy oil, but rather about controlling your breakpoint on the flatter USBC pattern. For example my Lock out hooks my Paradox, but the Paradox is much more controllable on flatter patterns, while still giving me hitting power. Based on limited experience with the alpha crux and a lot of experience with the Lock, I would opt for the A Crux.
Look for stuff that will hit when you square up a bit, rather than stuff that you hope can open up the lane.
