If by high side, you mean pot-sized, then yes, 4.5x is pot-sized.
5-6x seems good here. Most of your profit against loose/passive 'tards is going to come from you raising their limps, and then c-betting and they fold. So if most of your profit comes from them calling a 4bb raise and giving up, increasing that raise size to 6x will increase your winnings by 50%.
