Ok my second thread hoping more of you have both models and can help me compare the two. I currently own the Ten. I really like them, they fit on my face well. The problem with them is after you start sweating and such they tend to fall off my face and move around and such after a few hours. I'm hoping the Pit Bull's will fix this problem but what I need to know is, does anyone have any comparison photos of the two side by side or can tell me how the fit is on the Pit bull? Also your opinions on each model and how they weigh in against each other? Should I get rid of my Ten's and get Pit Bull's or keep the Ten's? Helps, thoughts and ideas please.
