My shock came in on 26 Nov from the states - did my first race with it on 1 Dec, and I also got the Attack Link.
So my feedback might be based on the shock, might be the link or it might be both together - but damn i just love my bikes suspension now, the bike is so much better on the track, handling is awesome and even my tyre wear has improved.
So in short - Love it!!!
The only thing i did not like about the shock - when you do the install, there is no way to test if the Ohlins ECU is actually working, you plug it in and hope it works - but worked it did!!
The ZX10R - You'll go blind from over-exposure due to it's pure awesomeness!
