4 Stars Soft String

from NY wrote (June 06, 2015):

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.

3 Stars Nice String!

Great string if you have arm issues & still want power.

4 Stars Feel and Pop

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)

5 Stars perfect

My daughter using this string in the crosses with the Luxilon 4G 16L mains. Great Hybrid combination with power and control.
