Hi! I received (from TW) POG OS strung with Klip Natural gut 16 @ 60 lbs. I was very happy with this combination. Next I strung it with Luxilon Ace 18 and I am very disappointed... I can not describe details but lot of easy shots are out or net. I am not confident now and do not know what is wrong. Maybe Ace 18 is not good combination with POG? Maybe I got tension wrong (58)? Any ideas?
