compared VS/Outlast to VS/4G in matched frames today.
I think Outlast sort of won. Far more spin which tamed its greater power. Not quite as much control as 4G but more than enough.
Only open question: will Outlast's theoretically greater tension loss ruin its longer term precision?
Only on Talk Tennis can you find people who believe
that 10 feet of lead tape has no effect on a frame...
