Can anyone here compare the sidewall of the Karma to the Cortez?? I run the Karmas on my el mariachi and like them alot. Thinking about using the Cortez 2.4 in the back of my Yeti but am concerned about the sidewalls. Are they any thicker for the Cortez? The site says the knobs are taller and the weight is over 700g so I would assume so but would appreciate any real-world comparison...
