I've got Head Sonic Pro 17 at 42lb in my Prestige Classic Mid, and it's pretty dope: soft, good pocketing, little bit of power, getting great spin with it. I played well with Tourna Silver 7 Tour at 44lb, but it was a little too firm. Regular old Lynx 17 was also nice, but I get more spin from the Sonic Pro. Tier One Ghost wire makes some very thin gauges at great prices. Ball gets in and out quickly with GW and it seems like a harder stringbed, but not uncomfortable. GhostWire is a unique string in that it seems very stiff and crispy while not feeling harsh at all, but has great control, and nice spin in thin gauge, it's a little pingy in sound. I also like Gosen AK Control 17 strung a little higher. I like Ice Code 18, too ( great spin), but its just a little too muted for the flexy Prestige Classic and I get a little more pop and pocketing from the Sonic Pro.
