Considering how rare flats are (at least in my experience, I never once flatted in 7 years of racing), it's not worthwhile.
My mistake - I had read "220 grams" when what the tube box actually said was "120 grams." Oops...
Still, one could save at least 30 grams by going with the lightweight tube/sealant option. But, based on the replies so far, it's looking to "not be worth it..."
