Just strung my ki 5 with Pacific Tough Gut 16 (M) and Babolat Nvy 16 (C) at 62#cp. Thought I was going to get to play tomorrow, but couldn't get anyone to play. Will have to wait til next Friday. The Babolat is very smooth, elasticity is similar to most synthetics, and its really easy to install. The Pacific went in well too. Can't wait to see if the Babolat meets the expectations set by Shock Shield.
