Guitar player too, huh? You can safely skip the "professional" for me, but finding the perfect guitar strings clearly is another life goal for me too. Current favourite: DR Strings 12-52 (with a wound G-string) for C# standard tuning. There are so many parallels between playing the guitar and playing badminton when it comes to finding the "perfect" gear, it's stunning. A major difference being the numbers on the price tags though... So yeah, I feel like we would get along very well in the real world so make sure to say hi if you come to southern Germany at some point. We could go through my racket, guitar and beer collection. But back to topic - LN1 performs perfectly fine with lower tensions. I have a bunch of club mates who use it at 20'ish lbs. and it plays, well, like LN1 at a lower tension. It doesn't get slippery or stuff like that. On the pro side, you get a great durability before it actually snaps if you go lower. The question is why you want to string that Victor racket that differently than your main weapon.
