I was wondering when jumping around double satcheling should I still be holding W in mid air while strafing? (I am used to CS GO Straftring where you cannot touch W) and should I be crouching?

I feel like it would be a sick concept maybe with the classic awp vandal and odin and then like a dagger or something I still think the oni phantom is the best phantom in the game and it would be very cool to see it come out again on differ...

I get nervous before playing competitive because I know the things that are at risk, I was just wondering if some of you guys have it too.
