I use the beads first cuz in lessons the chewing of the leader between the two hooks so the trailer hook has less a chance of getting worn off on some teeth, but mostly for more color, I use neon green beads with some bright pink beads mixed in the middle, sometimes red. All I know is when I set it up this way, I was catching fish, so I just keep doing it ya know, one of those things, and I keep telling people I fish with to do it too. The Ace_Hi looks awesome in the water with the beads, I know it doesn't look the same 120' down, but hey, it works so I'm sticking to it. But then again, whatever ya fish with the most is probably gonna work the best for ya. You know how that goes.
