They're great cabs. I have the same as Ste and, whilst it can be a pain to carry sometimes, I've had worse. The skids on the bottom help too. For sheer brute strength and kicking out bass, this is a great cab. As Ste said, I think Monz's 2x12 is even bassier, but also heavier. I wouldn't say it was too bulky or uncomfortable to carry, they're just right to get your arms around and mine fits in a Fiesta with the seats down along with a fender bass case and an orange valve head, with some room to spare.
Speaking of cabs looking cool, they have a shedload of options to customize the cab to how you want it. Pretty much anything can be done. I went for a vintage style and think it looks cracking
Good luck in your quest.
