To answer your question, the Critical Theory is long and strong on heavy oil. Whereas, the Lucid will be earlier and stronger off the spot. Its not bad to have both, they actually make a pretty decent combo.
On a personal note, being left-handed and owning a Critical Theory, if you as a right hander dont have a CT in your bag, YOU LOSING! Lol! Everyone clamours for long and strong on heavy oil and that is the flippiest ball on heavier patterns I've ever thrown. I love watching the reaction of mine making oil look stupid.
