Yaa Via is light, easy, tasty, potent enough to blow the doors offa any other system when also considering weight. Only bother is creamer. We usually buy the little single creamer sauces,but longer than a night or two its too much volume, weight, worry about popping, so we take the Trader Joes instant coffee which is much cheaper than Via and has creamer mixed in, but its less potent so we supplement it with a via packet.
We may just take Via and some flavored powder creamer.
In any case I believe that a french press+ beans, while better in quality, is not worth the weight when compared to the reasonably lower quality, but significantly lighter instant mixes. YMMV
FWIW I live in a coffeecentric area and am therefore, by default, a quasi-coffee snob, and Via gets the job done for me.
