Just pour scent free, salt free sticks and tubes and use... LEAD WEIGHTS!!!!! DUH!!!!!
Seriously, I use the "sugar flakes" for weight in stick baits and they work great.
I happen to think salt free stick baits used with a small giggy head are more deadly than the "salted" baits. You will also get the benefit of having translucent baits if you pour them with nothing and just use a weight or weighted head. Crystal clear baits with just glitter are killer!!!
Can't comment on tubes but sure you can do them salt free, scent free..
