I agree with Bibio, avoid progressive springs for the reasons stated, plus, they are synonymous with excessive fork dive on initial front braking.

I cant see why progressives make dive worse as surely thats down to damping again? A spring of what ever type compresses a certain amount with the weight its supporting and then when its subject to more load such as from braking it will compress more depending on its spring rate.
If you have the spring rate correct for the required sag theres not much you can do about how much more it will compress under load. In fact if anything progressive should give less dive travel as their rate goes up the more they are compressed....
