I've given up on worrying about the weight of my gear. As it is, my live rig consists of:
Sequential Circuits Split 8, Roland JX8P, Roland TR-505, TWO Korg Poly 61s, microKorg, DX7 MKI, Roland Juno 60, Roland Alpha Juno 2, Yamaha AN1x, Korg Monotron Delay, Ace Tone FR3, Zoom RT123, Korg Electribe MX, Korg Electribe EA 1, a tube pre-amp, a memory man, a rack mount master FX unit, a Kaoss Pad Quad, a mixer to fit all that c**p, and the stands/cables/power stuff to go with it.
As you can tell, weight is just at the point of a non factor.
MU Modular (Moog, Dotcom, STG, Analog Systems, and Moon modules), MS20 (x2), Microbrute, Electribes (EA-1, EMX), microKorg, AN1x, Nord Lead 2x, Blofeld, Alpha Juno 2, DX7, JX8P, Poly 61 (x2), Split 8, TR-505, Monotron Delay, Ace Tone FR-3, Paia Fatman
