After tinkering for a couple years with all sorty of sting from Poly, to Nat Gut to Hybrid, you name it , I tried it. This one is my new go to and am done messing around. Off the string bed I did not love it at all, but give it an hour or so . I strung at low tension 44 , next time will bump it up to 48 . It is the goldilox of strings it just does everything well not exeptional. Control is the best, has spin, touch, feel. It is not stiff or mushy . I have had elbow issues in the past no problem. Lower launch angle for a string like this , but I like that . I can hit out more and they stay in. I purchased from my local tennis shop and stoked. Hope it comes in other colors someday. Just give it a little break in, you will enjoy these.
