What do you think of various spring makers for the Prelude?

Anybody know the pros/cons of the various brands, specifically the Tein S-Tech (1.4 inch drop), Eibach Pro Kit (1.3) and Suspension Techniques Sport (1.25)?

I'm interested in a mild drop with increased firmness and reduced roll, but nothing too harsh. I won't replace the shocks at this time. I'm leaning toward the ST Sport right now because I can get a good deal and match it with the ST rear anti-sway bar. I think the ST Sport is a linear spring, so I'm not sure how it will compare with the progressive rate ones like Eibach.

Thanks,
