Im glad that you are having success with it :)
The aspect of my game Im working on most right now isnt a specific position its finding pathways to navigate where I dont have to switch my grip to finish. Like say I do a double underhook hooksweep and I land in half guard top, I go to the no hand pass because thats what I already have a grip for and then I go for something like a farside armbar because I get it off my far underhook
The pearl harbour transition was the first one I came up with, the controling grip the sweep comes off of is basically the fishing grip for the following submission
