Pete, here's a very rough estimate:
Broadleaf 350 20x
Carolina Brights 20x
Blank 20x
Lenox 30x
Red Hindu 40x
Uzit 80x
Drum 100x
Broadleaf 460 150x
Brown Lenox 180x
Brown Old Mill 240x
These are estimates and will of course vary from player to player.
But if you're serious, Chris B. is selling a Drum and BL460 right now on the BST board.
