yes of course, but this is how you add a spherical to a cartesian vector.
if you want to add 2 spherical vectors, just add them element-by-element...

what machine are you running ? how "many" vectors ?
on modern machines you really shouldn't notice (if you don't have 100 millions 
of vectors each second, but then you will have to wait for faster hardware 
rather than faster abstractions/externals)
