I bought these when I started feeling like my Vater Power 5A's were a bit too heavy. They felt and still feel perfect. I play rock and heavy metal and I still get a great amount of power, and I am very weak as far as muscle comes. The tip is pretty small but I have not had these break, mostly because I have improved my technique.
My Power 5A's are starting to feel pretty good now, so I switch between these two. I definitely recommend you buy a pair to maybe test them out, but I can assure you they will feel nice. They have the right weight for rudiments when it comes to control and speed.
