1. Bab Tonic+ BallFell 16G
2. Pacific Classic 16G
3. Klip Legend coated - distant 3rd as coating is not up to par
I have never had any problems with permature snapping with these guts and they all have great feel. Legend is very tricky to string as the coating is not good but Bab and Pac string very easily if you are careful like you should be with any gut.
I suggest trying Tonic+ or Classic if you want to experience high quality gut at a reasonable price.
