I'm currently trying to find the best string available for my Li-Ning N 50 1st gen, currently strung with NS 30 30lbs digital w/o pre-stretch, I really love the hard feeling and hitting sound, but it suffers from tension loss pretty easily. I wonder which Zymax can get the same feeling in terms of: 1. Power 2. Hitting Sound 3. The hard feel on NS 30 Consider all strung with same tension 30lbs w/o pre-stretch. Cheers
Z65 or Z67 will match it for power and sound, but you won't get the NS30 feel from anything other than BG80 or Victor VS850. I'm an NS30 user myself, and I thought the tension holding was great at first... but measuring the string frequency over time has made me realize it's not great. Prestretch helps, though.
