im not sure about the comfort level on the few options you listed below, ive tried a few and found no comfort in them and/or their reputation seems to suggest otherwise
it could be just me, feel is a "personal-thang", after all
Pro Supex Micro Ace, (itried 18 version, could feel TE coming on after first hit, I cut it out right away, never looked back)
WC Scorpion 17L, (agree, I liked this one, powerfull early generation poly)
Tourna Big Hitter Blue 16, (never tried, but I think its like topspin-cyberblue, which I never though of as soft, even though reports say otherwise)
Solinco Outlast 17, (this ones easy, never tried,, but SOLINCO does not make soft polys, never!!, not a fan)
WC Ultra Cable, (4sided poly, most of these shaped polys tend to be on the crisper side, I curious about this one, will try soon)
Topspin Cyber Flash 17 (like this one and 1 agree, a buttery muted unique soft feel,, one of my early generation favorites)
as for the Volkl Cyclone Tour, its a early generation poly with medium power, its shaped and twisted, thusly making it a bit more crisp than a round poly of similar type/gauge
