You can get a double ended poly brush tipper from a musical mail order company called Lark In The Morning (I don't have the address handy but the tipper works pretty well on my 26"). Or you could order a drummers poly or metal brush from the Vader drum stick company. The one I have allows the brush to recede into the handle. I do not recommend the metal brushes as they leave marks (kind of like pencil marks) each time you strike the head (unless you've got a plastic head, which is what they're normally used on). Good luck!
