I will however (when i move over to do some mma) do a night of judo and possibly 1 night of wrestling per week to help my mma game. I feel that somebody who jumps into mma straight away will get, good at everything. Whereas I would like to pay attention to my stand up, and my ground game, so i am very competent and accomplished in BJJ and thai boxing when i start MMA.
Also I feel it is a lot to take on at once to jump into mma and some people dont take to it without a good martial arts background of some sort. When i do start some mma (most likely when i get my blue belt in BJJ) I will encorporate wrestling, thai, judo and my BJJ. one night a week if thats all i can do.
