I'm looking for the most fierce and harsh strings available. I really don't want to use BB ALU Power again, to me I think it looses a lot of tension quick. I am looking for 1.25 or bigger Metal Like strings. Doesn't have to be polyester, could be a hybrid. I want such a harsh string that It feels like I have metal wire in my racquet. I have good strong arms and can take harsh vibrations. I string my ALU Power to 62 and 65 once. Something GUN METAL will be good. Something that will make the racquet feel like a ball hitting a brick. IF you guys know any strings similar to these features, PLEASE Let me know as soon as possible. Thank you all so much.
