    Couple people have recently with great results, so they say. Would like to myself, but have other things in line first. I know the progressive springs can be found at bikebandit.com. Can't remember who's done it. A quick browse might help...

    mainexj550 just did. Do a search of his recent posts. Don't know how to give you the link. Post is titled "Fork and steering bearing update today"

    Many have done it, myself included, and a worthy upgrade it is.

    Use a good dedicated fork oil - in my experience it works better than plain engine oil. I went with 15 wt fork oil, cuz I'm a fat guy - YMMV.

    The hardest part is getting the spacer size right. I think they recommend something like a 1.5" spacer, but in my bike it ended up being about 5" long to get any pre-load at all.
