You don't "catch up" with current Jiu Jitsu you discover your game through trial and error. Some submissions work well for others. I want hit Gogoplata's, DLR/Berimbolo and Kimura's but for some reason they just don't click, but I do have a decent triangle, RNC and guillotine. I also love foot locks, especially toe holds. These are submissions I have had success with and find news way to hit them and adapt them. Do I ignore kimuras, birimbolos and gogo's, no way, I hope to have a fucking Miyao like spiral guard one day. The minute you start discarding moves because you are bored of them you are giving up all the reps you put into that move and risk it not becoming something you slay people with. Look at Roger Gracie, took people down, passed their guard, obtained mount, collar choke from the mount. BOOM, 10x Mundial Champion and he used basic shit. Take what you got and make it your own. Find a way to make it fun, beautiful and yours.
