I strung at 55lbs my kblade tour 93 with Kgut 16 and after 2 sets I feel my triceps sore and almost on 2nd I was scared of serving. I used NXT 16 before and didnt notice any pain at all. With kgut I can also feel more shock coming. will the string losen up and be better or should I just give up on this string and move on ? Doesn't look like Arm friendly string at all.
