Tungsten Predator Eyes

More expensive but the smaller profile allows me to use them on smaller flies . I use the red mostly, I don't know what it is but the fish seem to key in on eyes that color .

Tungsten Bead eyes get your streamer down much quicker than Bead chain eyes and a little faster than lead eyes, but that little bit of time which translates to depth as it falls through the water column, is the difference between reaching the predators waiting to ambush the bait fish or hopefully your streamer.

Great weight, they are hard to break but they are really expensive. Depends on where you're fishing if they're worth the price
