Biphase 16G ... Good feel and pretty durable. Much easier on the elbow as advertised. My string of choice from now on
After a few years of hitting w/ polyester strings (RPM Blast, Tier One Firewire), I contracted tennis elbow. As a result, I switched to the X-One BiPhase strings. Very soft, gut-like string. Xlnt for arm pain. Nice touch. But nowhere near the power and spin of poly. That's the trade-off. Would likely be good to mix w/ a soft poly in a hybrid fashion.
Great string if you have arm issues & still want power.
Good power and touch, but not as durable as other multifilaments I've used. I prefer the Kirschbaum Touch because of $$ and durability. Good cross string for a hybrid (ie 4G or RPM Blast)
best synthetic tennis string ever, perfect feeling and touch
Read online reviews, seemed to get very positive ratings. Have only tried it once but seems like a very good overall string.
Great feel. My favorite string.
My daughter using this string in the crosses with the Luxilon 4G 16L mains. Great Hybrid combination with power and control.
