Bought it on the Bay, so unfortunately, no cover. I have a 6-bag, but I like having the individual racquets in their own covers too, so that they're not rattling around and chipping at each other when I'm tossing my bag around
The Pro Line II is a really good string IMO. I'm just trying WeissCannon's Silverstring in this Gamma to compare it to the Pro Line. For me, the PL has been very soft, comfortable (at the proper tension, that is--if strung high, it can feel boardy, like most other strings), and plays just fine. In fact, when I had my old AG100 strung with Bab VS natural gut, I hated the feel; I thought the PL felt 1,000 times better to me (although maybe part of that was the racquet difference, too).
I'm just trying to see if the WCS might be even better
