[Ducati] 900SS service manual: Ducati or Haynes?

[Dez]

I have all three, and have crossreferenced and  double checked  pictures and 
text when tackling new tasks.

The factory book, is accurate, but not as clear perhaps as the Haynes with 
all its supporting pictures. LT Snyders 2V book offers specific no-nonsense
procedures for routine and common tasks.

When headed to the garage for any Duc service that I haven't done before, I 
have the Haynes and Snyders books in hand, and most likely have leafed thru 
the factory manual, pre planning my work.
