Question about Drumsticks? Drummers please answer?

Nylon is a hard plastic so you will get a more crisp "ping" when you ride on the cymbal. It also might help in rudimentary lessons like practicing rolls where you have to be precise. However, sometimes they slip off even though they are glued on strongly! I prefer the natural wooden tips because, as an unbroken extension of the stick itself, the stick is more dynamically responsive. The stick needs to "bend" ever so slightly and the plastic tip hinders that subtle flexibility.
