Did a search and found very little in relation to comparing the two. Found one old poll comparing the two,where Pit Boss wins 18/14 votes. (I wonder if the results would be the same today.) I was wondering if anyone had a comparison pic of the two. I own PB I's and PB II's, but have never been fortunate enough to see/handle a C-Six in person. How do they compare in size. What are the frame measurements of a C-Six @OakleyFrankFMJ. Hmmmm. Lets try that poll again. I love the Pit Boss because it is a testament to Oakley's style and innovation. Same can be said for the C-Six. Aggressive style points go to Pit Boss, I think C-Six wins in engineering and materials. Pit Boss is a def win in the price category. Next to my X-Metals, Pit Boss is a close second favorite. With that said, I'm going to vote C-Six. Without ever having handled one, it is a tough choice, but from what I can tell in the pics they look darn solid. I've never heard anyone say anything bad about them, and they are just on another level in my book. I'm sure I will eventually own one, but for now I'll have to do with pics. Please cast your votes and explain why you chose what you did.
