So I do about 99% gi training. Been training for almost two years. Went to a no-gi class after ages yesterday, and felt like fish out of water - got obliterated (sparring from the knees). Without gi grips had no clue what to do first, so played defensive (open guard from back) and got smashed and subbed. Tried guard passing but again, without grips didn't get anywhere. Anyone have similar experiences, or have any tips?
