I second Flip's advice. On my 96 M900 -which also had Marzocchis at front I went the Hyperpro route to start with using PDQ in Slough (primarily as money was tight). Made a difference for sure but not as much as I was expecting.
Eventually I went the same route as Flip after doing some research on the forum (mainly provided by Flip tbh!!) and after a discussion with same knowledgeable chap- the legendary Richard at Maxton. The GP20 cartridges and set up by Maxton made a huge difference - the symptoms described in Flip post I knew very well. Maxton are great in my opinion but cheap they aren't and if you do go for it try not to catch them at the start of the race season as you are likely to have to wait a long time to get them back. Let us know how you get on if you take the plunge - be it in the shallow or deep end
