Hook & Loop MMA Shin Guards by Combat Sports-Combatsports.com I'm thinking about buying these shin guards because they're on sale right now. Has anyone use these shin guards before? I'm going to be using this for stand-up only. For those that have used these shin guards, should I get a medium or a large? I'm 5'8" and weigh only 140 lbs. I might get a pair for my cousin who's only about 130 lbs, so would a medium would be good enough for her too?
