Hi Dnatasha, I think the weights idea needs further elaboration from you because on a forum like this with no visual media to aid someone may misinterpret an idea and injuries may follow. You might want to take a pic to show how you actually practice with weights.
However, in my opinion, all it takes is learning the right grip, be loose enough to not choke the sticks and learn how to control the bounces in time. Weights may result in bigger muscle development and we all know big muscles slow down movement...try to ask Arnie to sprint for you!!
Yup, so a pic from you will really help and also a brief account on your personal development with the use of the weights will help heaps too.
Cheers!
