I picked one up from Jayson and can say it is the best I have used.
Done Kamui, Masters, Great White, Predator.. Absolute opposite of Kamui virtually no (none seen by eye) chalk dust left on hands or table. seem to be lasting a bit longer maybe this is because what you use stays on the tip. Not half on tip and half on your chalking hand. I chalk center outward and with other chalk my middle and ring finger catch all the falling chalk with other chalk.. Five hours of play hand is clean....Left hand dirty only from the table HAHAHA
New tip chalked once played 3 racks without rechalking...Pretty good as most know new tips require rechalking often at first.
A bit expensive yes
I think they put price so high because they know to be best.
At least I gonna buy it anyways
