That was more for comparison (whiteline is somewhere on the 2nd page). Most of the bars in the link have both their size (e.g. JBR=32mm) and their difference from stock listed, so you have something to compare to.
You really need to try an upgraded bar (install it, drive lots, adjust, drive more) so you have a reference point, else you are just guessing.
IMO the Whiteline bar is perfect for a daily driven car. Stronger than stock (big difference) and you can adjust it to your liking. Plus it's easy to get in Aus and if you decide that you want something more cardcore, you can always sell it here.
