Ian, obviously you and Wendy are only happy cos they do the job you want them to. It's funny though cos when comparing the Hagon's with the Progressive's, it needs to be recognised the Hagon's use the quadrate progressive springs action which is similar I believe with the progressives.
The other factor that make these a good cost effective alternative is that the damping and spring rates can be chosen according to your weight and riding style ie soft, medium, hard and extra hard. Not bad for less than $300AUD / $250AUD
