Just want to know if this is normal for K Gut. I mean it is a a multifilament and all and I do like the way it plays. But... well here's my description So I strung it up, and you know as you run your cross through the main, it'll create little dents on the mains as you pull on the crosses. Well those little dents are visible almost an entire hole down. I did pre-stretch it. Is this normal for this string?
