Go to guitar center and ask. First find out what type of drums he plays, tell them, and they should be able to help you. Drum sticks don't cost that much. you can get a cheap (but bad) pair for like $3
You could always do some research on the internet. I'm sure they have ratings somewhere about drum sticks... Probably everything is on the internet... Well information wise..
I honestly have no idea...I don't play the drums but my sister does, and there are like MILLIONS of different types of sticks, and I'm not sure I think that she likes the ones that are wooden but with plastic tips.
