Progressive fork springs ?

I have recently fitted a set of Wirth Progressive fork springs to a set of Le Mans mk2 forks.
The advice from the Guzzi supplier was to fit the tighter wound section of the spring to the top ?
I just wanted to see if anyone else has fitted these and which way round did you fit them ?
does it matter ?
I just have a feeling that they should go with the tighter wound section to the bottom
of the fork leg ?

any ideas ?
 
theoretically, it shouldnt matter, cause the tighter wind will always compress first, regardless of orientation.
 
It doesn't really matter, but I agree with the supplier. The tighter wound side should go to the top of the fork. That way the tighter coils, which compress first, do not become unsprung mass the moment they coil bind.
But the difference is so small I would not worry about it if you have already put it together the other way.
 
ok thanks for the comments, doesnt sound like it would make much difference ?
I will give it a try as they are and can always swap it over
