I'm playing the 16ga right now in a full setup at 56/54 and also enjoying Beast. I've done several gut/beast hybrids in the past and also liked them.
I enjoy the feel most as it is quite crisp without being stiff. Also seems to maintain its elasticity longer than many other brands.
It's on sale now so I'm thinking about getting more.
