I've just about gone through a reel of Signum Pro Tornado and am ready to reorder. I was thinking about buying a reel of Hyperion too, but was hoping for some feedback from someone who has used both. I've strung Tornado/Spiral Flex for over a dozen people and have had 100% positive feedback. Is Hyperion the same string as Tornado, just not reheated and twisted, or is it a different string. Signum Pro lists Hyperion's gauge and color as diamond black and 1.24mm. Tornado is listed as anthracite and 1.23mm. The difference in gauge could be from the twisting process. Anyway, has anyone played with both and can give an opinion?
