Hello to all !

I have a question about bead weight.

I am looking to pick up some tungsten beads, and I noticed that there are both slotted, and countersunk.
The sizes are pretty much standard.

But ,
Are the countersunk heavier then the slotted ?
Looks like more metal is missing from the slotted then the countersunk ?

Has anybody check this out ?

Have a fantastic weekend!
