I have more Billiards in my collection than any other shape. I love a good billiard.
To my eye, this 1966 Dunhill LB is the best shaped Billiard I have ever come across. There is no real ring grain so the blast is nothing special, but the shape is what I am talking about.
For ring grain this Rad Davis has some really nice grain.
Another nicely grained pipe is this Jose Rubio.
Both of the nicely ring grains also have some nice shaping as well.
I could go on and on but you get the idea. I stopped buying smooth pipes with killer grain or Birdseye as I learned you cannot smoke grain and I can get 2 pipes for the price of one. Chasing grain is fun but it is also very expensive and I am still putting kids through college and law school. You need to get the shaping down before you go for smooth pipes or pipes with killer sand blasts. You will get there if you keep working hard at it. Good luck.
