i have done straight grappling and done vale tudo/mma type training; i prefer the mma training, i don't need to be a specialist on the ground. The main reason i started training or sparring was to learn self def/how to fight; so being excessively technical on the ground was never something i wanted to do or tried to do. i do appreciate focusing on the grappling cus it made my overall grappling flow better; not sooo staccato, not that it still isnt stop and go (it is). Its just not as bad as it used to be, an i opened up my submission game whereas i was just working on def takedowns, escapes, base and standup grappling; i actually started to round out my sub game, i.e. heel hooks, kimura, arm triangles, triangles and developing a somewhat eff guard game (its still basic at best, but now i don't just def w/it0 nowadays i just grapple-but when i feel like doing otherwise, i meet up w/people and we do mma type sparring just to remind me of the holes pure grappling creates in an mma or self def situation.
