I should add one more note on VS/4G. After roughly four weeks of play I asked my stringer to measure tension loss on the SB. Based on his ERT values immediately after stringing and then four weeks later he said tension loss was about 10%. During that time I had two formal practice sessions, a couple of friendly matches, and several casual sessions with wife and kids as well as a few solo serve practices. Less than my summer schedule but a reasonable amount of play.
The VS is seriously notched by the 4G and even the 4G is getting dented by the VS at this point. But while a little bumpy the mains still slide across the crosses and I don't need to realign them at all...they move back by themselves. When I move the crosses by hand you can hear a very loud snapping noise as they lock into the gooves worn in the mains.
Pure Storm GT mod: 337g, 8.5 HL, SW 328
