I think it depends on skill level. I have the Triumph manual and like stated above it is geared to mechanics. Very little how to stuff they just assume you know all the little stuff. So if you already know basics the Triumph manual is good if you need hand holding then the Haynes combined with the Triumph manuals is probably best.

On a side manual note the old 500cc manual showed the oil lines backwards in the diagram. It had the return on the feed and vise versa.

I learned all I need to know about life by killing smart people and eating their brains.
