i would like to know if it makes a huge difference which i buy considering i want to do mma. i prefer the third because im accustomed to wrestling and those gave me a nice fit while not being bulky. i appreciate all opinions! and if there are nice headgears that you recommend that aren't too hard on the pockets i would gladly listen to your recommendations.
Thanks everyone
