^^^ thats it, its about give and take.
its good to let whites get a tap from time to time, you have to let people know they have done something right so you give them it.
its not like they will tap you in a real match but its a learning thing,you cant just smash them all the time like you said.
im a small ww and im 5,8 tall and there is nobody my size in my class's,im matched with either bigger or smaller all the time.
when i do roll or spar with peeps from other gyms who are my size im a lot stronger and quicker than they are from
mixing it up with big and small on the daily. its like sparring with big heavy gloves and switching to mma gloves after. pow.
