i'm not sold on the glass beads, yeah they make the baits clearer but that's about it. salt is cheaper and is also a lot safer to handle/use. Don't have to worry about a pet or child getting a hold of them. anything that scratches aluminum might not be the best idea to use either. in terms of durability, i don't really care if one bait catches 1 fish or 20 fish, i'm there to catch fish not see how long 1 bait can last. salt is also natural to the earth, glass beads maybe are similar because glass is made from minerals, but still man made. yeah the plastic isn't natural either but that part is kind of necessary.
