I used rip control 17 at 55-57lbs on my mg rads and recently felt a lack of power. tried sppp 17 at 50lbs and wow what a difference. switched back and forth of my rip control 17 and sppp on two matched racquets, rip control is soft comfortable and dead, I much prefer the feel of sppp, a lot more power and feel. want to buy a reel of poly for my daily string. Can someone recommend a spinny and powerful, somewhat durable poly? I have sppp, cyberflash, solinco bite, snakebite, power cord as some of the options.
