i hate rolling on the ground, the last fight i had i sort of lost because the guy "grppled" me down and put me in a lock where he repeatadly smashed me in the head and that sayed you can probably tell that i do a striking art. even though the guy got me on the ground im sure his back was just as scratched up as mine, btw my oponent does wrestling and he was doing it a bit longer than i have karate. I tell you this but, i was really drunk when i got into the fight and could hardly stand on my feet, if you ever seen someone throw a punch only to land on the ground... that was me, and before i hit the floor i messed him up prety good, and i had mates wating around the corner "who didnt know i was fighting as i went to defent my honour, by myself" who would have killed the guy shold they have known, therefor im sticking to my striking art, hope that helped
