The reason they went with the jewel core HAS to be the fact that the HB is 2 peice. From what I know, a 2 piece ball since it has no filler. You gotta make 14lb, 15lb, 16lb cores....just like the quantum's...
With a normal core like what's in the new Badger I feel they don't have to make as many different weights for the cores--right?
It's more cost effective, plain and simple.
