The clutch pedal isn't noticebly light or heavy. It doesn't seem far removed from the clutch action normal to Honda. The change itself feels slightly bulkier, probably down to heavier components gearbox side.
Ive not driven an Accord Derv but Honda tend to be lighter than other manufacturers, im not sure if its down to the hydraulic clutch or if they make them that way so that small Japanese laides can press it easily. When my parents had a Golf the clutch was much stiffer than my Honda.
