oh my gosh, I am totally green with envy ush:! You are one lucky gal!
I guess it depends on what effect you're after... Are you after the "WOW" standout effect? (As if LV bags don't have that effect already... hehe ) If so, the MC Black speedy will sure do the trick But I like my LV's to be more subtle... So I personally prefer the Damier Speedy.
