Well, the thing about Volkl Cyclone and Cyclone Tour is that they are still talked about 15 years after release. Not many strings get that sort of longevity in this short attention span world. The ONLY poly that has the most attention is obviously Luxilon Alu Power/Rough, but that comes from the pros using it. Even RPM Blast and HyperG have gone away.
I still buy Volkl Cyclone 18L whenever I'm in TW. For less than $70 a reel, it's one of the most cost/performance value polys out there. Of late, I find that by dropping tension by at least 10%, and using the 10-15 seconds extended pull stringing method, much of the tension drop is taken out without hurting the elasticity of the string. Prestretching (-10% reference, 5% prestretch) causes it to play stiff and dead, especially using Sergetti. Fine tuning is probably necessary to find the right personal feel.
