I use rods, No. 9, and Break Free. Mostly because that's the way I've done it for 30 years. I don't deal well with change. They all work, it's just what you like. I've never actually used a bore snake, but a rod goes both directions easily, the bore snake is a one-way affair. Granted you can run it the opposite direction, but it seems much slower. They are more compact for field use I guess.
