I did think a lot about that - but in the end I decided that if (a big if) I ever gig on guitar again then I'm not sure I'd want to gig anything other than my JCM800.
And due to medical issues - I want wheels.
I can cope with the in and out of the car bit, but more than that - with the amount of surgery I've had over the last few years - wheels are important. Cannot be arsed with sack barrows though. It's just more to pack.
The Big Twin 2 was also thought about - but boot space is limited. It would fit, just, but not with the other stuff I have to fit in as well.
