arzh,
the closer the nodes (the circular rings around a fired rattan) the better. these close nodes tend to be heavier because it is more compact. so, as a beginner you should possess lighter sticks to practice precision and speed, then the close node, heavier sticks, for power. also, get urself bahi (center of coconut trunk) and kamagong (iron wood) sticks, just cuz all the cool eskrimadors have one or the other or both. when in an actual confrontation, be sure to have the heavier stick, because the light ones will bounce back hard on your face when you hit someone's skull with it.
cheers...
