I personally went with the Andreani cartridge because I regularly do track days with the bike. However I reckon correct springs and tapered compression needles would be good enough.
The main problem for fast pace riding is the progressive spring.
I read so much of that blog, made a comment, and got an email from Matti. Very comprehensive info on a lot of modifications in that blog.
I've ended up ordering Ducati M1100 Monster Evo K-Tech Compression Adjusters (07-15) , 118-250-026-001 FF PISTON KIT MARZOCCHI 26mm , and HPFS FORK SPRING PAIR from their Oz agent http://www.ridedynamics.com.au/ at Yatala near Brizvegas.
No real idea which kit would be better.
At the rear, I've replaced the Sachs spring with an Eibach 0700-225-650, $140 + local freight.
