Babolat RPM Blast
RPM Blast 1.25 has an octagonal shape black string that gives heavy spin & maximum control to your game. It has a stiffer feel but is used by many professional tennis players such as Nadal, Thiem, Tsonga & Wawrinka.
I will say the RPM Blast created slightly more spin than other polys I tried, but the harsh lifeless feels wasn't my liking.
My all time favorite string! for me, this string works wonders. I'm able to hit solid groundstrokes, my volleys are very crisp and sharp, and my serves/overheads are overwhelming for my opponents. This string is softer compared to other poly's that I;ve tried.
Very nice string. I switches to this after using ALU Power for a long time.
