Sorry to nitpick, but MX preferencing isn't really "weighting" in the 
strict sense of the word. Equal-preference MX records are randomized, 
but within that randomization, each record is given the same weight. And 
unequal-preference MX records are only used for failover.

SRV records have a real weighting mechanism, but unfortunately very few 
clients use SRV records, including the crown jewels, web browsers.
