I had a client offer to trade me his (heavier, 8 lbs) MIM Classic Series 60s body straight across for my '09 Classic Vibe body(lighter, 7.1 lbs). Honestly, mine is pretty sweet and looks beautiful, and light, made of Alder same as his. Anyone know what big differences between the two might be? Is the MIM wood quality better? Would it be in my best interest to "upgrade" to a MIM CS?
