First let me say I LOVE GRAPPLING, but I have zero desire to compete in sport BJJ. If I ever have a future in combat sports, its in MMA, not BJJ. While I respect the intricate berimbolos and 50/50 stuff, I think its applicability is largely in IBJJF and It would not be the smartest allocation of time for MMA.
All of the schools in my area are GI, sport style gyms. There is a MMA gym, but I want to learn it from someone clean and with a strong lineage. This leaves me in the middle of things. Learn from a MMA gym, and also learn wrestling and clinching, or go to a BJJ school and just grab the collar and lapels.
I know alot of people say rolling in the Gi makes you better No-gi, but I highly disagree. If all of your attacks come from the collar, then you probably have a sub-par overhook and underhook game, which is way more important for MMA. What is your opinion? What would be smarter for me to do?
