I use a Kevlar blend and it was quite a bit stiffer. The string is as tough as nails but stretches much more than Kevlar. I would love to try it in a blend with synthetic gut. It should play softer than my current set up. This is one of the most durable strings I've used.
String has good pop but lacks control and tension maintenance.
Strings absorb shock well. The only down side with this string was how greasy it felt while stringing. The overall playability surprised me. I liked the durability and it maintained tension. This string was surprisingly comfortable.
