True. Karate is very front heavy. It's always good to know both (Karate and Muay Thai) since both stances have their benefits, but people can tell if you start to shift a lot.
I thought Mendes won 2 rounds. I like Beneil Dariush. He seems to do the basics extremely well. Nothing fancy. Just sound technicals. Sort of like the Danny Garcia of MMA or what GSP used to be (when he first started). If he builds on those I think he can go really far.
