I can probably reduce what I'm carrying now as the guitarist has got XLR cables to run to the main speakers. Small suitcase (carry-on luggage size) with IEC cables, 6-way and 10-way mains extensions, XLR leads which I don't need as we've gone to wireless mics except for the times when the wirelesses might not work for some reason, XLR to TRS leads that I don't need to carry around any more but will forget on the one occasion that I need them if I don't, and a few spare jack-jack instrument cables. One small aluminium case for wireless, MS60-B, and the combined power and jack-jack lead to go between them and the amp. Second small aluminium case with amp, assorted speaker leads, and a second combined power and jack-jack lead just in case. Smaller aluminium case with wireless mics in it. Larger aluminium case with wired mics and drum mics in it that we never use.
