JRT6, I am a purple belt and have landed the classico sweep(with different grips) from half guard on brown belts.I was dumbfounded when I landed it for the first time on a higher belt
. Since then it has become my go to sweep from half guard as I am constantly trying to improve it.
In reality, if you time it perfecly you can land the sweep with no grips,by just doing the backwards roll ( I have yet to do this on higher belts yet).
I think it was mentioned on other half guard threads by other posters, but the way I set it up is from Z half guard. I get the grips on the leg and sleeve and go for the scissor sweep from half guard..most guys generally do not get swept but they push back into you to maintain base..and boom..you go for the classico sweep. As mentioned in the video, it is imperative that you turn the opponent with your grips,like turning a steering wheel.
