I think it's a cool grab, but definitely not a textbook bow & arrow. It looks more like the grab in b-dogs dub at freestyle.ch. I definitely want to add a more pronounced one like TJ does.
And for the people who can't turn or whatever while tweaking a grab, that's because the keyboard you have can't handle as many keys being pressed at once. It changes depending on your keyboard and also which keys are pressed. So for example if you're keyboard lets you hold A+S+D+F at the same time, you might be able to add G as the fifth key but not H. It has to do with the way the circuits are laid out.
I'm trying to work on a fix where instead of holding S + E to tweak left safety, you'll also be able to press S and then switch over to E and it'll do that same thing if it's done within half a second or whatever.
