TopLine Maxx vs. LA Performance struts?

[evilC]

Riseabove, I run a Spax PSX kit that is progressive with I think 110lb primary rate. This is with a stiffened front end and I feel that when pushed over the country roads around here they work very well although I would have liked to try a marginally softer rate. The original rate was 80lb/in and I understand that the Topline coil overs are around this rate. I don't get any harshness and the grip is very impressive overall and too much for the lowly 1600tp that is fitted - it is unstickable.
