I'm looking for a bit of input from those of you who currently own either of these amps or have owned one in the past. I'm thinking seriously of down-sizing my current rig and investing in a high-end combo...probably one of these two. Realistically, what size gigs would one of these cover well, either with an extension cab or without? Have you found yourself underpowered, and if so, how large was the venue/volume requirement? Finally, both these things are as heavy as my Goliath Sr....are they tough to carry around? Small size is fine, but if it weighs a ton, it's not that much better. Thanks in advance for any info!
