Comments: First, let start by saying IR019m NOT a heavy hitter. String broke the very first time I used them on my Pro Kennex KM 175 FFT (tension 33lbs). Very disappointed, going back to Ektelon Strings.

Comments: Great string for the money.  I'm not a string breaker but have had great durability with this string and love the playability.  A great upgrade from factory strings to add a little pop to any racquet.

Comments: Great string all the way around. The only thing is that 17gauge is going to break on the higher level players fairly quickly, but this is also true with all 17gauge string. If having too many breaks, than switch over to 16gauge. I break my strings often, but the playability of 17gauge string I believe is worth it.

Comments: I bought 2 packs, one for me and one for a friend. My friend however broke these strings in exactly 2 weeks time. He's an A level player and a hard hitter, so if you hit hard and are above C level, I suggest getting the Ashway Killfire 16.

Comments: Broke during 2nd game after freshly strung at 33 lbs! Always loved Ashaway as my go-to brand for tournaments or competitive playing. I'm a medium speed swing and the string still broke during the 2nd game. Choose another version, but always give Ashaway a chance, especially those strings with Zyex! There was no resiliency felt, and the ball seemed dead on the stringbed without much trampoline effect to it. Lacked control and power overall when it lasted. There is vibration with this string, no matter how I tweak my dampener and handle wrap. You get what you pay for for this particular string version.
