I read a little more on the formula change and now Babolat uses 7 thicker strands of gut instead of the previous 15 thinner strands. My only gripe is that I've had 3 VS gut jobs pop overnight in the last 3-4 months. I was never able to be sure why. But this hasn't happened in a while, though.
VS (in my case Team) / 4G is a sublime hybrid.
I've also had BT7 pop in my bag overnight 3 times. The original formula never, never, never did that too me.
