I don't mind dealing with the 4CM to be able to use the preamp of the amp, as I think it can be a nice addition to some patches. You know, the more possibilities the better ;)
Regarding the 5W, I can always mic the amp, and that's my main question, will be noticed the difference in sound quality, the nice valve sound everybody loves, or the POD is too close to hear the difference unless you compare it with good amps at proper volumes?
Unfortunately weight makes a huge difference living in a big city with no car.
