Dave at
http://www.besttippers.com/bodhran_tippers_017.htm looks to be doing some topendy tippers
i've also used thin timbale sticks...cut them down to 6" or 9" and rounded the cut end off, or even done that to thin drum sticks, to try to get some inexpensive topend style tippers
the 9" plastic chopstick with some extra weight works pretty well... weight is darn close to some of the other topend sticks i have
personally... i find the actual tippers made from a fiddle bow to be far to light in weight for me...but that is just my preference
