I personally wouldn't bother with:-

you are having cruise control... It never really works that well with manual cars.
To be blunt, that's nonsense. If you actually plan your direction and speed properly, then cruise control is easy to use. In fact, you begin to see how inconsistent other drivers' motorway speeds are.
Also, certainly in my car (with factory cruise) you can 'accelerate' using only the cruise control stalk. The only major downside - to me, anyway - is you'll still have to change gear then re-set it.
get back into 6th gear before you can "resume" your set cruising speed
Factory fit cruise works above 19mph, so are you suggesting it should only be used in 6th gear..?
Heck, I potter about town with it set at 29 to avoid speeding fines.
