I found your string specials while searching some racquets to demo. There was Klip Legend natural gut, Prince Syn Gut Multifilament, and Technifibre NRG2 that had great savings. I was wondering what you meant by "installed string only". Does it only apply when you purchase an unstrung racquet, and you (TW) string it up for a discount on strings... or what? I just want to clarify before I order. Thanks in advance.
