They don’t compare to kitty string. Kitty string is great string, but if you are looking for top of the line then you need Toxic. I’ve tried everything except great whites and their regular string. BG1’s and Snakes are my favorites. They say Snakes are thinner than BG1’s, but Snakes feel thicker to me. I like them both, but if you can only try 1 I would recommend BG1’s. They are by far my favorite string.
