Sonic Pro in short
Head Sonic Pro combines unique co-polymer polyester with a soft molecular construction for good touch and comfortable feel. "A great all-round string that delivers on its promise of control and comfort." Received remarkably low stiffness scores compared to most polys tested. Power level slightly higher than average for a co-poly. After an hour of hitting it softens up and feels livelier. Best in the mid-50s tension range - at higher tensions it plays too dead, lower tensions lose control. Budget-friendly at $8-12 per set.
Revolve in short
Wilson designed Revolve so the main strings could snap back more effectively, multiplying the player's efforts into heavier spin. The tri-polymer construction includes a low-friction additive to make the string more comfortable when swinging at higher speeds. Playtesters found it on the soft end of the spectrum - "felt soft, but not mushy." With great control and lots of spin, Revolve is a solid option for advanced players and experienced intermediates. As a budget-friendly option, it's significantly cheaper than similar strings like RPM Blast.
