I thought tein put their forte program on the shelf?
I with #3 - would like to see some good coilovers as options.
The problem with just adding springs is that they are not matched with the struts. One may be softer than the other, or vice versa. When you get a matched set they are able to perform at the same rates and givepoints. It's the system that the previous poster was referring to, but applied to aftermarket. It is possible with the right options and research you could pair struts and springs from different companies, but you would need details and other's experience to make them an effective combination.
