Hi All, I've just tried ZM70 @23lbs and like it a lot. Compared to my usual string BG65ti the ZM70 has better power and better feel. I'm considering giving ZM62 and ZM67 a try and would appreciate advice on what tension I should use? I've heard that ZM62 should be 2lbs lower than usual, is this correct? Worried about durability of ZM62 so hopefully stringing at a relative low tension of 21lbs should last longer? Has anyone had experience of ZM62 at low'ish tensions? Lastly, my stringer doesn't stock ZM62 or ZM67 so can anyone recommend where I can buy these in the UK? Thanks!
