Thanks JossFan!
I am very glad finally we will get an answer here.
I guess since the price of quality tips like Ultraskin and milk dud (pooldawg8) here are so affordable, that there is no need to look around for something else.
I've installed a half dozen or so over the last month and everyone so far seems to be happy with them at this point. It beats spending $15 or more for a tip. These are local league players that chances are wouldn't know the difference between the hit of a Moori vs Kamui vs Talisman -- so, IMO they are an affordable option
