Just bought a v-con 17 but it plays too light. I can't handle the heavy balls and my timing is not always right. Before this i used the pro staff classic and that racket felt more stable. I added 3 grams at 3 and 9 o'clock each. How much weight should i add to the handle to get the right balance again. Already have added an overgrip because my grip was too thin so this already added some weight too. I hope someone can help me with this???
