Babolat Addiction is a great multi to use as a crossstring for any poly. If you're stringing a lot, buy both the RPM and the Addiction in reels and maximize your savings by carefully measuring the needed lengths. You'll get a few extra half-sets of the Addiction so you can buy a couple of extra sets of the RPM to try and even it out.
If you're playing 16 or 17 RPM, use the 16 Addiction. If the RPM is 18, try Addiction 17.
Despite all of life's bumps and bruises, I'm still committed to making this world better one smile, one laugh at a time, every day!
