try 1-looking your faces. like not just 1-looking it, try to know where your bar is located, or if you have it all solved, or all opposite.
a bit more advanced is to do a bit more extra moves or manipulate it a bit so you always have the bar in the ideal position. this ideal position is to different to everyone depending on their PBL algs. mine are all the the back so i try to put the bar at the back as much as possible in my solves.
this will take a lot of practise but these will definitely get you fast 2x2 times. LBL is kinda underrated, so if it only takes a few more moves, then do an LBL layer.
