Needed more Taom V10, so picked up Dr V's chalk and a cube of Pagulayan.
I use Taom for cleanliness - any properly applied chalk works fine in my experience.
Dr V's Titlist chalk is clean, but not quite as clean as Taom. Titlist chalks dusts up a bit like Masters. Taom almost never does.
The Titlist chalk is a little "creamier," though, and feels nicer to apply. Not sure I will switch from Taom, but I like Titlist so far based on how it goes on.
Haven't used the Pagulayan yet, but if it's just reformulated Taom in a square shape, I wouldn't have anything to say. Chalk shape is no big deal to me.
Now Fedor Gorst is about to come out with his own chalk.
Best thing that could happen is all the competition drives down prices. Shocked that Kamui still charges $30 or more for some versions of its chalk!
