Having blown out my back in summer 07 and then being in a car accident the following November and through diet and exercise shed 45+ pounds, I am a huge fan of lightweight gear. I just bought an Epifani UL 902C head. Dual 900 watt amps @ 4 ohms each. Great sound, 14 pounds. Nuff said. If you have a crew to set up your gear, use whatever heavy gear you like. I don't think Phil lugged his gear but I could be mistaken. I'm not married so I don't have that as a variable in GAS issues. Love your spouses, your backs and your bass playing activities.
