Some shops still carry the old formula if you think you prefer it. When I was last in France I had our product manager walk me through the difference. It is a proprietary technique and although there will be strong backlash to this statement, it has not changed the way it plays if you don't know you are playing with a new version.
I 100% disagree. When I bought the gut with BT7 I was not expecting any difference in the way it was going to play. But I was shocked at how much stiffer it felt. Strung in the same racquet, at the same tension, by the same stringer, on the same machine.
P.S. I've been using Babolat VS Gut since the juniors.
