I've used the Pagulayan chalk tonight; it was a long session, about 4.5 hours.
After I got the V10 in blue, I read somewhere that it is not as good as the green; I don't understand why colour should make a difference, but when I ordered the Pagulayan chalk, I went with green to test that claim.
I'm assuming here that both the Taum V10 and the Pagulayan are the same chalk!
I find the Green Pagulayan a bit softer than the Blue V10.
It's easier to apply and hold better to the tip, especially the phenolic tip of the break and jump cue, but also to the playing medium tip.
Considering I prefer the square shape to the round shape of the V10, I think that I have a winner.
As the chalk is a bit softer than the Blue V10, it looks like it wears out a bit quicker. I still prefer it; I wish it was taller, like the cheap chalks, like Master.
