Several
I have 2 shafts with PoolDawg 8's Milk Duds, one with a Black Kamui Soft and one with a medium Talisman. They are all good tips in my opinion.
I often wonder if break cues and tips are not over rated for all but the top tier players and that ain't me.
I think of all the great players who played great pool with all kinds of tips. Efren is a Milk Dud guy, Shane was a Brown Kamui guy then a Milk Dud guy and many more used other tips.
For me I guess I will try a new tip once in a while, but the Dawg's Milk Duds and the Talismans are good tips and don't cost 20 bucks a pop!
