Or don't you notice a weight difference since the center of gravity of the 2X30L is closer to your back compared to the 60L? That's an unusual set-up.

Actually it isn't unusual at all. One outfitter even sells the setup.

That's similar to what I use and it is quite comfortable to carry (until you pack those barrels full ;)). The two 30L barrels do keep the weight  closer to your center of balance. That's another advantage to the 2 30L barrels I forgot as your food disappears you can balance the load between the two barrels.
