I have PPA 16 @ 58 and Babolat Addiction 16 @ 55 now.
The verdict: PPA wins. The addiction strings have no grip to them, I have to work too hard for spin. The PPA are great: very soft so absolutely no pain. Plenty of grip, can produce all the spin I want.
But, not happy with the poundage. When I get both PDs restrung, I'll go 60 on both. Balls tend to sail out on lower tensions, so hopefully I can get a little more control.
