Trevor....I'm not playing the age card on you. If you can't discern the answer from what I've given you.....them I'm giving you too much credit. Really....it isn't that hard. I (like Matt) disagree that the smaller diameter fixed head .....even though it has perpendicular blades......is optimal. It has a 1.25" cutting diameter.....no matter which way you slice it (pun, intended). The rage's cutting "diameter" (albeit linear) is 2".

What are you seeking an answer to that I haven't given you numerous times?
