I play mainly heavy, fast paced metal on an 8 string with 10's tuned to standard, so I have an enormous amount of tention on the strings. I burn through a Jim Dunlop nylon pick in one sitting every time, and at times would have to grab a fresh one in a single sitting. It is absolutely not the case for these. These picks take all of the abuse I can lay on them. Session after session, I'm on the same pick.
