The problem is that more preload will not make it exactly stiffer: the forks will have more travel when breaking and hitting bumps, but at the expense of having less travel when extending (when the wheel goes over a hole for example). As Anzacinexile said if springs were linear more preload would just change ride height. But as the springs are dual rate you will have less soft travel rate and more stiff travel the more you add preload. I do not know if I am explaining it well sorry.
Use 20 oil. There is little difference between 10 and 15, specially if they are from different brand they could be almost the same real viscosity.
I still think oem springs are decent, the problem is the lack of damping makes them seem too soft, and the dual rate is too soft and later too hard trying to mask that. My ace's springs are soft and the bike is 229kg and 86 myself, and they work perfectly. Maybe somebody changed them? I have to investigate it.
