Both rigs work. I have some Capps rigs, but that just cause I won a raffle. I usually git the rigs at Grizzly Jigs, the ones on a cardboard skinny toilet paper roll. They cheep and work, but they hard to pull loose from a hang up.
I tie my own rigs with the weight on the bottam. Change weights with the snap on bottom. There are lots of ways to double rig.
I like double minner rigs period. I usually only use them when I fish by myself. But not always.
Nutin better than a double, except a triple.
