Also available in a convenient reel, the performance of Alien Black Diamond can only be described as "out of this world." The standard co-polyester construction is taken to new heights thanks to the unique extrusion process that combines stretching and heating in order to align the chain polymer molecules into a single direction. This ensures consistent playability while the crosslinked mesh of chains increases durability and control. The most noticeable advantage of Black Diamond is that their synthesis process results in a polyester based string with exceptional retention, ensuring that the playability remains relatively constant throughout the life of the string. Our playtesters found that this string had a surprising amount of feel and control without feeling harsh. We feel that this string is best suited for advanced baseline players looking for a solid combination of precision and ball pocketing with lasting durability and consistency.
