if your present stem is 90mm , the 90mm adjustable can move the bars up a bit, but it will also move the bars back towards you. Same length, angle more upwards= closer to you.

good luck experimenting with diff changes.

also, the tilting the seat back a smidge trick can change the feeling for your back and pressure on hands, but it really depends on your bar height and how ye ol cajones feel about X amount of upwards tilt of the front of the seat.
