Hi Tony. I've gone for the Bergantino CN212. It's a cracking cab and I ran my DB751 through it at it's first gig last Saturday. Very punchy sound and bags of volume. It only weighs about the same as one GS112 but, as it has two handles, it forces me to use both hands to lift it, which is much easier on my injured shoulder. At something like 47lbs it's very light for a 2x12. I really liked the sound of my GS112s and I had to think long and hard about replacing them. It was a leap of faith to get the Berg, but I think I can justify it to myself.
Cheers
Pete
