I've settled on this racket and I am now experimenting with strings and lead tape. I play mostly 4.0/4.5 doubles and occasional singles. I have an "old school" game and prefer aggressive net play. I'm not a frequent string breaker and string my own rackets. I've added lead tape at 3 & 9 o/c and currently have one strung with E-matrix and the other with Yonex 850 Pro Spin. I'm contemplating ordering some Iso-Speed Professional which I liked in my HPS 6.1. For those that have been using this frame for a while, what strings have become your favorite and if you use lead tape, what locations worked for you? Thanks.
