I’ve tried a lot different strings. I once had a guy who I made a deal with on the BST ask me about strings and bearings. I wrote a very long pm out of my usual need to explain my experiences in great detail. I won’t do that here, but after I sent the pm he said that what I wrote was great stuff and should be stuck to the top of one of the forum sections. Anyway, when I first started I was very into boutique strings, especially BG1 Yellow Jackets. I still like those strings quite a lot, but after trying pretty much everything except YYSL Type X I’ve learned that Fat Kitty String is usually the best bet once you get into learning more complex tricks that require good tension and the ability to whip well.
Strings like Toxic Snakes, Dragons, BG1’s, and many different homemade strings that are made to be very whippy are very great at that, but they don’t hold tension well enough. Strings that hold tension well usually don’t whip with the speed you would like, or they just don’t feel right. YYSL AMMO had that effect on me. There is a string that holds tension better than anything I’ve tried and whips really well, but it just doesn’t feel right for some reason. Especially after it has broken in.
Fat Kitty String is what most all competition players use, and there is a reason for that. They are labeled “Fat”, but they are no where near as thick as most boutique strings. They hold tension great until they get worn, and they whip well for a good amount of time. When you put a new Fat Kitty String on your yoyo the first couple of whips you do have the perfect amount of speed to them, but after those it begins to lose the umph. The good thing is that they are relatively cheap for a large amount. If some company could make a string that will feel and play exactly like Fat Kitty does when you first put it on, but make it last much longer than the first couple of minutes then I believe you could crown a “Best String”.
