I had a chance to directly compare Topspin Cyberflash 1.25mm and SPPP 1.18mm as mains in a hybrid setup. Goal is to tame the power of the Warrior OS, have great control and not aggrevate TE. Racquets: Prince Warrior OS String: Cyberflash or SPPP mains at 54lbs Head Rip Control crosses at 59lbs Power: Cyberflash has the edge here. This string has more power with a muted feel at impact. Some trampoline effect with this power, however. Control: Pinpoint accuracy with the SPPP. Excellent control where I can dictate the length and location of shots. Cyberflash has a tendency to spray, which comes from the noticeable trampoline effect. Perhaps Cyberflash should be strung tighter, or maybe it is the thicker gauge. Spin potential was noticeably better with SPPP and I can place blocked shots much better. Feel: Soft and powerful with Cyberflash, especially with volleys. With SPPP, more board-like and stiff. However the odd thing is that my TE was aggrevated by Cyberflash, even though it feels softer. I played for hours with the SPPP and never had an issue with my arm or shoulder. After only an hour with Cyberflash, my arm was hurting. Overall, SPPP at 1.18mm is the best for my situation. I am surprised that Cyberflash actually absorbed shock less than SPPP, at least in my frames.
