That's a band I'd like to see, and a guitarist who likes to hear the bass is a rarity, most I've played with like to hear the guitar! Totally agree, if you're going on the road, especially overseas, you're carrying a lot of weight. I suspect that if you opted for some of the gear mentioned above, and perhaps had a look at Barefaced cabs, you're going to save your back a lot of work for a very good tone. The questions remains whether it's the same tone (although if you dropped Alex at Barefaced an email he'll certainly do his best to advise you on cab choice given your current rig).
