Comments: The economical price of these strings is what attracted me. Upon use I was pleasantly surprised. Quite soft for a poly, nice control and feel, excellent vibration/shock control, lower on the power side and found good spin in the first few hours of play. I strung it on 55lbs on a Dunlop Biommetic 100 and Wilson Burn 100. It was one of my first experiences in moving into new strings after I moved on from OEM SG from racquets and really enjoyed it.
