Non Tungsten Slotted Cones

[Stonedfish]

This is a cool looking pattern. It gives me some ideas for some saltwater cutthroat flies.
I did some google searches for non tungsten slotted cones but didn’t come up with much. I’d prefer something lighter then tungsten.
Anyone have a source?

I didn't find anything either. I do wonder how much those cones actually weigh, as there is a huge cavity and a missing slot. The 5mm is listed as "small," with an "extra small" 4mm option available. While those sound huge in bead terms, perhaps they aren't because of all the missing material.

That said, I don't see why you couldn't lock in a (slotted) bead at the jig bend, or if needed attach the bead via a pin (à la balance leech) so that's it's just off the shank/jig eye bend. Via a pin you could then put any size/weight/color of bead you wanted (and you don't need a slot in it.)
