Image is everything, right? Agassi first started using Kevlar/Aramid strings in the 80s. What is Kelvar/Aramid? It’s what bulletproof vests are made of.

Kevlar is actually has more tensile strength (resists stretching) than polyester but this combo is tried and true since Agassi first started using it on tour. Remember that mullet?? And those denim shorts?? OMG.

He first used “synthetic gut” in the crosses (I don’t recommend doing this as it would break your arm) but then later switched to natural gut in the crosses. I’ve actually tried this combination before and it works quite well but the strings move around all over the place.

Natural gut isn’t for everyone (for the cost and maintenance) so I’ve substituted it with a string that is almost as soft as gut, just as powerful and WAY more slick. It’s made of the same material the put on your frying pan. Fluorocarbon. Also known by the brand name: Teflon. Because of it’s non-stick nature, it allows those Kelvar main strings to impart more spin than natural gut would allow. It is an amazing combination. The overall stiffness is similar to a full bed of stiff “synthetic gut” but the Kevlar fibers help absorb vibrations better than you would think.

• string at 50lbs max
• best suited for softer racquets with a max stiffness of 63RA
• Not suitable for those who have sensitive joints and have had tendinitis
