It is a great idea to have weighted sticks as this effects the sound you get significantly, especially on cymbals.
These stick are very well made and you can be sure that they will be the same as the last pair which is more than I can say for other brands. They are also a very good price.
I have bought some Vic Firth Steve Gadd sticks and some Vater sticks which varied considerably in weight, so much so that I can't use some pairs and so I have swiched to the Agner brand.
I was very dissapointed with Vic Firth with whom I was in correspondence with and complained to, they tried to tell me that any company who weighted sticks would soon go out of business. I would therefore urge others to try Agner to insure this doesn't happen.
Altogether an excellent product.
