What.. you don't like voodoo?
Scientifically.. there is more mass and more string tension. I think both contribute to more harmonic content in the vibrating string and thus a more complex and interesting sound. That's enough science for now.
I find heavier strings give more "body" to the overall tone of the guitar. Also I can dig in harder. I find 10s sound like rubber bands and 9s like teflon tape, but I am exaggerating and it's all so personal!
Yeah, AFAIK Hendrix played 9s and his tone was alright :icon_biggrin:
Those infinite feedback sustains work better with lighter strings.
Oh and before you discount rubber bands, these sound killer: http://www.largesound.com/
